+# Oozie Logging
+
+<!-- MACRO{toc|fromDepth=1|toDepth=4} -->
+
+## Default Oozie Logging
+
+Oozie's logging properties can be configured in its log4j properties file (default is `oozie-log4j.properties`). Most log messages
+are configured by default to be written to the `oozie` appender.
+
+The default configuration for the `oozie` appender is shown below.
+
+### Default Configuration
+
+
+```
+log4j.appender.oozie=org.apache.log4j.rolling.RollingFileAppender
+log4j.appender.oozie.RollingPolicy=org.apache.oozie.util.OozieRollingPolicy
+log4j.appender.oozie.File=${oozie.log.dir}/oozie.log
+log4j.appender.oozie.Append=true
+log4j.appender.oozie.layout=org.apache.log4j.PatternLayout
+log4j.appender.oozie.layout.ConversionPattern=%d{ISO8601} %5p %c{1}:%L - %m%n
+log4j.appender.oozie.RollingPolicy.FileNamePattern=${log4j.appender.oozie.File}-%d{yyyy-MM-dd-HH}
+log4j.appender.oozie.RollingPolicy.MaxHistory=720
+```
+
+In this configuration, the active log file will be named `oozie.log` and all old log files will be named `oozie.log-yyyy-MM-dd-HH`
+(where `yyyy-MM-dd-HH` is the time that that log file was created; e.g. 2012-07-21-05). All log files are in the same directory
+(whatever `oozie.log.dir` is assigned to). A maximum of 720 older log files will be retained. The active log file is rolled every
+hour, so 720 old logs means that they are kept for 30 days before being deleted.
+
+To keep all old logs instead of deleting them, `log4j.appender.oozie.RollingPolicy.MaxHistory` can be set to `-1`.
+Additionally, `log4j.appender.oozie.RollingPolicy` can be set to `org.apache.log4j.rolling.TimeBasedRollingPolicy`, which has the
+same exact behavior as `org.apache.oozie.util.OozieRollingPolicy` except that it does not delete old logs.
+
+### Restrictions
+
+In order for Oozie logging to work 100% correctly, the following restrictions must be observed (described below and in
+the `oozie-log4j.properties` file):
+
+* The appender that Oozie uses must be named "oozie" (i.e. `log4j.appender.oozie`)
+
+* `log4j.appender.oozie.RollingPolicy.FileNamePattern` must end with "-%d{yyyy-MM-dd-HH}.gz" or "-%d{yyyy-MM-dd-HH}".
+If it ends with ".gz" the old logs will be compressed when rolled
+
+* `log4j.appender.oozie.RollingPolicy.FileNamePattern` must start with the value of `log4j.appender.oozie.File`
+
+## Previous Default Oozie Logging
+
+Oozie previously used the logging configuration shown below as the default for the `oozie` appender. The other appender that Oozie
+writes to still use a configuration similar to this.
+
+### Previous Default Configuration
+
+
+```
+log4j.appender.oozie=org.apache.log4j.DailyRollingFileAppender
+log4j.appender.oozie.File=${oozie.log.dir}/oozie.log
+log4j.appender.oozie.Append=true
+log4j.appender.oozie.layout=org.apache.log4j.PatternLayout
+log4j.appender.oozie.layout.ConversionPattern=%d{ISO8601} %5p %c{1}:%L - %m%n
+log4j.appender.oozie.DatePattern='.'yyyy-MM-dd-HH
+```
+
+In this configuration, the active log file will be named `oozie.log` and all old log files will be named `oozie.log.yyyy-MM-dd-HH`
+(where `yyyy-MM-dd-HH` is the time that the log file was created; e.g. 2012-07-21-05). All log files are in the same directory
+(whatever `oozie.log.dir` is assigned to). All older log files are retained. The active log file is rolled every hour.
+
+### Restrictions
+
+In order for Oozie logging to work 100% correctly, the following restrictions must be observed (described below and in the
+`oozie-log4j.properties` file):
+
+* The appender that Oozie uses must be named "oozie" (i.e. `log4j.appender.oozie`)
+
+* `log4j.appender.oozie.DatePattern` must end with either "dd" or "HH". If it ends with "HH", the log will be rolled every hour;
+if it ends with "dd", the log will be rolled every day.
+
+## Other Oozie Logging
+
+While Oozie can technically use any valid log4j Appender or configurations that violate the above restrictions, certain
+features related to logs may be disabled and/or not work correctly, and is thus not advised.

+# Oozie Quick Start
+
+These instructions install and run Oozie using an embedded Jetty server and an embedded Derby database.
+
+For detailed install and configuration instructions refer to [Oozie Install](AG_Install.html).
+
+<!-- MACRO{toc|fromDepth=1|toDepth=4} -->
+
+## Building Oozie
+
+### System Requirements:
+ * Unix box (tested on Mac OS X and Linux)
+ * Java JDK 1.8+
+ * Maven 3.0.1+
+ * Hadoop 2.6.0+
+ * Pig 0.10.1+
+
+JDK commands (java, javac) must be in the command path.
+
+The Maven command (mvn) must be in the command path.
+
+### Building Oozie
+
+Download a source distribution of Oozie from the "Releases" drop down menu on the [Oozie site](http://oozie.apache.org).
+
+Expand the source distribution `tar.gz` and change directories into it.
+
+The simplest way to build Oozie is to run the `mkdistro.sh` script:
+
+```
+$ bin/mkdistro.sh [-DskipTests]
+```
+
+
+Running `mkdistro.sh` will create the binary distribution of Oozie. By default, oozie war will not contain hadoop and
+hcatalog libraries, however they are required for oozie to work. There are 2 options to add these libraries:
+
+1. At install time, copy the hadoop and hcatalog libraries to libext and run oozie-setup.sh to setup Oozie. This is
+ suitable when same oozie package needs to be used in multiple set-ups with different hadoop/hcatalog versions.
+
+2. Build with -Puber which will bundle the required libraries in the oozie war. Further, the following options are
+ available to customise the versions of the dependencies:
+ ```
+ -Dhadoop.version=<version> - default 2.6.0
+ -Ptez - Bundle tez jars in hive and pig sharelibs. Useful if you want to use tez
+ +as the execution engine for those applications.
+ -Dpig.version=<version> - default 0.16.0
+ -Dpig.classifier=<classifier> - default h2
+ -Dsqoop.version=<version> - default 1.4.3
+ -Dsqoop.classifier=<classifier> - default hadoop100
+ -Djetty.version=<version> - default 9.3.20.v20170531
+ -Dopenjpa.version=<version> - default 2.2.2
+ -Dxerces.version=<version> - default 2.10.0
+ -Dcurator.version=<version> - default 2.5.0
+ -Dhive.version=<version - default 1.2.0
+ -Dhbase.version=<version> - default 1.2.3
+ -Dtez.version=<version> - default 0.8.4
+
+ *IMPORTANT:* Profile hadoop-3 must be activated if building against Hadoop 3
+ ```
+
+ More details on building Oozie can be found on the [Building Oozie](ENG_Building.html) page.
+
+## Server Installation
+
+### System Requirements
+
+ * Unix (tested in Linux and Mac OS X)
+ * Java 1.8+
+ * Hadoop
+ * [Apache Hadoop](http://hadoop.apache.org) (tested with 1.2.1 & 2.6.0+)
+ * ExtJS library (optional, to enable Oozie webconsole)
+ * [ExtJS 2.2](http://archive.cloudera.com/gplextras/misc/ext-2.2.zip)
+
+The Java 1.8+ `bin` directory should be in the command path.
+
+### Server Installation
+
+**IMPORTANT:** Oozie ignores any set value for `OOZIE_HOME`, Oozie computes its home automatically.
+
+ * Build an Oozie binary distribution
+ * Download a Hadoop binary distribution
+ * Download ExtJS library (it must be version 2.2)
+
+**NOTE:** The ExtJS library is not bundled with Oozie because it uses a different license.
+
+**NOTE:** Oozie UI browser compatibility Chrome (all), Firefox (3.5), Internet Explorer (8.0), Opera (10.5).
+
+**NOTE:** It is recommended to use a Oozie Unix user for the Oozie server.
+
+Expand the Oozie distribution `tar.gz`.
+
+Expand the Hadoop distribution `tar.gz` (as the Oozie Unix user).
+
+<a name="HadoopProxyUser"></a>
+
+**NOTE:** Configure the Hadoop cluster with proxyuser for the Oozie process.
+
+The following two properties are required in Hadoop core-site.xml:
+
+
+```
+ <!-- OOZIE -->
+ <property>
+ <name>hadoop.proxyuser.[OOZIE_SERVER_USER].hosts</name>
+ <value>[OOZIE_SERVER_HOSTNAME]</value>
+ </property>
+ <property>
+ <name>hadoop.proxyuser.[OOZIE_SERVER_USER].groups</name>
+ <value>[USER_GROUPS_THAT_ALLOW_IMPERSONATION]</value>
+ </property>
+```
+
+Replace the capital letter sections with specific values and then restart Hadoop.
+
+The ExtJS library is optional (only required for the Oozie web-console to work)
+
+**IMPORTANT:** all Oozie server scripts (`oozie-setup.sh`, `oozied.sh`, `oozie-start.sh`, `oozie-run.sh`
+and `oozie-stop.sh`) run only under the Unix user that owns the Oozie installation directory,
+if necessary use `sudo -u OOZIE_USER` when invoking the scripts.
+
+As of Oozie 3.3.2, use of `oozie-start.sh`, `oozie-run.sh`, and `oozie-stop.sh` has
+been deprecated and will print a warning. The `oozied.sh` script should be used
+instead; passing it `start`, `run`, or `stop` as an argument will perform the
+behaviors of `oozie-start.sh`, `oozie-run.sh`, and `oozie-stop.sh` respectively.
+
+Create a **libext/** directory in the directory where Oozie was expanded.
+
+If using the ExtJS library copy the ZIP file to the **libext/** directory. If hadoop and hcatalog libraries are not
+already included in the war, add the corresponding libraries to **libext/** directory.
+
+A "sharelib create -fs fs_default_name [-locallib sharelib]" command is available when running oozie-setup.sh
+for uploading new sharelib into hdfs where the first argument is the default fs name
+and the second argument is the Oozie sharelib to install, it can be a tarball or the expanded version of it.
+If the second argument is omitted, the Oozie sharelib tarball from the Oozie installation directory will be used.
+Upgrade command is deprecated, one should use create command to create new version of sharelib.
+Sharelib files are copied to new `lib_<timestamped>` directory. At start, server picks the sharelib from latest time-stamp directory.
+While starting server also purge sharelib directory which is older than sharelib retention days
+(defined as oozie.service.ShareLibService.temp.sharelib.retention.days and 7 days is default).
+
+db create|upgrade|postupgrade -run [-sqlfile \<FILE\>] command is for create, upgrade or postupgrade oozie db with an
+optional sql file
+
+Run the `oozie-setup.sh` script to configure Oozie with all the components added to the **libext/** directory.
+
+
+```
+$ bin/oozie-setup.sh sharelib create -fs <FS_URI> [-locallib <PATH>]
+ sharelib upgrade -fs <FS_URI> [-locallib <PATH>]
+ db create|upgrade|postupgrade -run [-sqlfile <FILE>]
+```
+
+**IMPORTANT**: If the Oozie server needs to establish secure connection with an external server with a self-signed certificate,
+make sure you specify the location of a truststore that contains required certificates. It can be done by configuring
+`oozie.https.truststore.file` in `oozie-site.xml`, or by setting the `javax.net.ssl.trustStore` system property.
+If it is set in both places, the value passed as system property will be used.
+
+Create the Oozie DB using the 'ooziedb.sh' command line tool:
+
+
+```
+$ bin/ooziedb.sh create -sqlfile oozie.sql -run
+
+Validate DB Connection.
+DONE
+Check DB schema does not exist
+DONE
+Check OOZIE_SYS table does not exist
+DONE
+Create SQL schema
+DONE
+DONE
+Create OOZIE_SYS table
+DONE
+
+Oozie DB has been created for Oozie version '3.2.0'
+
+$
+```
+
+Start Oozie as a daemon process run:
+
+
+```
+$ bin/oozied.sh start
+```
+
+To start Oozie as a foreground process run:
+
+
+```
+$ bin/oozied.sh run
+```
+
+Check the Oozie log file `logs/oozie.log` to ensure Oozie started properly.
+
+Using the Oozie command line tool check the status of Oozie:
+
+
+```
+$ bin/oozie admin -oozie http://localhost:11000/oozie -status
+```
+
+Using a browser go to the [Oozie web console](http://localhost:11000/oozie.html), Oozie status should be **NORMAL**.
+
+Refer to the [Running the Examples](DG_Examples.html) document for details on running the examples.
+
+## Client Installation
+
+### System Requirements
+
+ * Unix (tested in Linux and Mac OS X)
+ * Java 1.8+
+
+The Java 1.8+ `bin` directory should be in the command path.
+
+### Client Installation
+
+Copy and expand the `oozie-client` TAR.GZ file bundled with the distribution. Add the `bin/` directory to the `PATH`.
+
+Refer to the [Command Line Interface Utilities](DG_CommandLineTool.html) document for a full reference of the `oozie`
+command line tool.
+
+NOTE: The Oozie server installation includes the Oozie client. The Oozie client should be installed in remote machines
+only.
+
+<a name="OozieShareLib"></a>
+## Oozie Share Lib Installation
+
+Oozie share lib has been installed by oozie-setup.sh create command explained in the earlier section.
+
+See the [Workflow Functional Specification](WorkflowFunctionalSpec.html#ShareLib) and [Installation](AG_Install.html#Oozie_Share_Lib) for more information about the Oozie ShareLib.

+
+<!-- MACRO{toc|fromDepth=1|toDepth=4} -->
+
+## System Requirements
+
+ * Unix box (tested on Mac OS X and Linux)
+ * Java JDK 1.8+
+ * [Maven 3.0.1+](http://maven.apache.org/)
+ * [Hadoop 2.6.0+](http://hadoop.apache.org/core/releases.html)
+ * [Pig 0.10.1+](http://hadoop.apache.org/pig/releases.html)
+
+JDK commands (java, javac) must be in the command path.
+
+The Maven command (mvn) must be in the command path.
+
+## Oozie Documentation Generation
+
+To generate the documentation, Oozie uses a Doxia plugin for Maven with markdown support.
+
+
+
+
+
+
+```
+$ mvn install
+```
+
+<a name="SshSetup"></a>
+## Passphrase-less SSH Setup
+
+**NOTE: SSH actions are deprecated in Oozie 2.**
+
+To run SSH Testcases and for easier Hadoop start/stop configure SSH to localhost to be passphrase-less.
+
+Create your SSH keys without a passphrase and add the public key to the authorized file:
+
+
+```
+$ ssh-keygen -t dsa
+$ cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys2
+```
+
+Test that you can ssh without password:
+
+
+```
+$ ssh localhost
+```
+
+## Building with different Java Versions
+
+Oozie requires a minimum Java version of 1.8. Any newer version can be used but by default bytecode will be generated
+which is compatible with 1.8. This can be changed by specifying the build property **targetJavaVersion**.
+
+## Building and Testing Oozie
+
+The JARs for the specified Hadoop and Pig versions must be available in one of the Maven repositories defined in Oozie
+main 'pom.xml' file. Or they must be installed in the local Maven cache.
+
+### Examples Running Oozie Testcases with Different Configurations
+
+**Using embedded Hadoop minicluster with 'simple' authentication:**
+
+
+```
+$ mvn clean test
+```
+
+**Using a Hadoop cluster with 'simple' authentication:**
+
+
+```
+$ mvn clean test -Doozie.test.hadoop.minicluster=false
+```
+
+**Using embedded Hadoop minicluster with 'simple' authentication and Derby database:**
+
+
+```
+$ mvn clean test -Doozie.test.hadoop.minicluster=false -Doozie.test.db=derby
+```
+
+**Using a Hadoop cluster with 'kerberos' authentication:**
+
+
+```
+$ mvn clean test -Doozie.test.hadoop.minicluster=false -Doozie.test.hadoop.security=kerberos
+```
+
+NOTE: The embedded minicluster cannot be used when testing with 'kerberos' authentication.
+
+**Using a custom Oozie configuration for testcases:**
+
+
+```
+$ mvn clean test -Doozie.test.config.file=/home/tucu/custom-oozie-sitel.xml
+```
+
+**Running the testcases with different databases:**
+
+
+```
+$ mvn clean test -Doozie.test.db=[hsqldb*|derby|mysql|postgres|oracle]
+```
+
+Using `mysql` and `oracle` enables profiles that will include their JARs files in the build. If using
+ `oracle`, the Oracle JDBC JAR file must be manually installed in the local Maven cache (the JAR is
+not available in public Maven repos).
+
+### Build Options Reference
+
+All these options can be set using **-D**.
+
+Except for the options marked with `(*)`, the options can be specified in the `test.properties` in the root
+of the Oozie project. The options marked with `(*)` are used in Maven POMs, thus they don't take effect if
+specified in the `test.properties` file (which is loaded by the `XTestCase` class at class initialization time).
+
+**hadoop.version** `(*)`: indicates the Hadoop version you wish to build Oozie against specifically. It will
+substitute this value in the Oozie POM properties and pull the corresponding Hadoop artifacts from Maven.
+The default version is 2.6.0 and that is the minimum supported Hadoop version.
+
+**generateSite** (*): generates Oozie documentation, default is undefined (no documentation is generated)
+
+**skipTests** (*): skips the execution of all testcases, no value required, default is undefined
+
+**test**= (*): runs a single test case, to run a test give the test class name without package and extension, no default
+
+**oozie.test.db**= (*): indicates the database to use for running the testcases, supported values are 'hsqldb', 'derby',
+ 'mysql', 'postgres' and 'oracle'; default value is 'hsqldb'. For each database there is
+ `core/src/test/resources/DATABASE-oozie-site.xml` file preconfigured.
+
+**oozie.test.properties** (*): indicates the file to load the test properties from, by default is `test.properties`.
+Having this option allows having different test properties sets, for example: minicluster, simple & kerberos.
+
+**oozie.test.waitfor.ratio**= : multiplication factor for testcases using waitfor, the ratio is used to adjust the
+effective time out. For slow machines the ratio should be increased. The default value is `1`.
+
+**oozie.test.config.file**= : indicates a custom Oozie configuration file for running the testcases. The specified file
+must be an absolute path. For example, it can be useful to specify different database than HSQL for running the
+testcases.
+
+**oozie.test.hadoop.minicluster**= : indicates if Hadoop minicluster should be started for testcases, default value 'true'
+
+**oozie.test.job.tracker**= : indicates the URI of the JobTracker when using a Hadoop cluster for testing, default value
+'localhost:8021'
+
+**oozie.test.name.node**= : indicates the URI of the NameNode when using a Hadoop cluster for testing, default value
+'`hdfs://localhost:8020`'
+
+**oozie.test.hadoop.security**= : indicates the type of Hadoop authentication for testing, valid values are 'simple' or
+'kerberos, default value 'simple'
+
+**oozie.test.kerberos.keytab.file**= : indicates the location of the keytab file, default value
+'${user.home}/oozie.keytab'
+
+**oozie.test.kerberos.realm**= : indicates the Kerberos real, default value 'LOCALHOST'
+
+**oozie.test.kerberos.oozie.principal**= : indicates the Kerberos principal for oozie, default value
+'${user.name}/localhost'
+
+**oozie.test.kerberos.jobtracker.principal**= : indicates the Kerberos principal for the JobTracker, default value
+'mapred/localhost'
+
+**oozie.test.kerberos.namenode.principal**= : indicates the Kerberos principal for the NameNode, default value
+'hdfs/localhost'
+
+**oozie.test.user.oozie**= : specifies the user ID used to start Oozie server in testcases, default value
+is `${user.name}`.
+
+**oozie.test.user.test**= : specifies primary user ID used as the user submitting jobs to Oozie Server in testcases,
+default value is `test`.
+
+**oozie.test.user.test2**= : specifies secondary user ID used as the user submitting jobs to Oozie Server in testcases,
+default value is `test2`.
+
+**oozie.test.user.test3**= : specifies secondary user ID used as the user submitting jobs to Oozie Server in testcases,
+default value is `test3`.
+
+**oozie.test.group**= : specifies group ID used as group when submitting jobs to Oozie Server in testcases,
+default value is `testg`.
+
+NOTE: The users/group specified in **oozie.test.user.test2**, **oozie.test.user.test3** and **oozie.test.user.group**
+are used for the authorization testcases only.
+
+**oozie.test.dir**` : specifies the directory where the `oozietests` directory will be created, default value is `/tmp=.
+The `oozietests` directory is used by testcases when they need a local filesystem directory.
+
+**hadoop.log.dir**= : specifies the directory where Hadoop minicluster will write its logs during testcases, default
+value is `/tmp`.
+
+**test.exclude**` : specifies a testcase class (just the class name) to exclude for the tests run, for example =TestSubmitCommand`.
+
+**test.exclude.pattern**` : specifies one or more patterns for testcases to exclude, for example =**/Test*Command.java`.
+
+### Testing Map Reduce Pipes Action
+
+Pipes testcases require Hadoop's **wordcount-simple** pipes binary example to run. The **wordcount-simple** pipes binary
+should be compiled for the build platform and copied into Oozie's **core/src/test/resources/** directory. The binary file
+must be named **wordcount-simple**.
+
+If the **wordcount-simple** pipes binary file is not available the testcase will do a NOP and it will print to its output
+file the following message 'SKIPPING TEST: TestPipesMain, binary 'wordcount-simple' not available in the classpath'.
+
+There are 2 testcases that use the **wordcount-simple** pipes binary, **TestPipesMain** and **TestMapReduceActionExecutor**,
+the 'SKIPPING TEST..." message would appear in the testcase log file of both testcases.
+
+### Testing using dist_test and grind
+
+Testing using [dist_test](https://github.com/cloudera/dist_test) framework with
+[grind](https://github.com/cloudera/dist_test/blob/master/docs/grind.md) front end might not work using the default 3.0.2
+version of the maven dependency plugin. It is necessary to downgrade to version 2.10 using
+`-Dmaven-dependency-plugin.version=2.10` .
+
+Maven flags for grind can be specified using `GRIND_MAVEN_FLAGS` environment variable:
+
+
+```
+export GRIND_MAVEN_FLAGS=-Dmaven.dependency.plugin.version=2.10
+grind test --java-version 8
+```
+
+## Building an Oozie Distribution
+
+An Oozie distribution bundles an embedded Jetty server.
+
+The simplest way to build Oozie is to run the `mkdistro.sh` script:
+
+```
+$ bin/mkdistro.sh [-DskipTests]
+Running =mkdistro.sh= will create the binary distribution of Oozie. The following options are available to customise
+the versions of the dependencies:
+-Puber - Bundle required hadoop and hcatalog libraries in oozie war
+-Dhadoop.version=<version> - default 2.6.0
+-Ptez - Bundle tez jars in hive and pig sharelibs. Useful if you want to use tez
+as the execution engine for those applications.
+-Dpig.version=<version> - default 0.16.0
+-Dpig.classifier=<classifier> - default h2
+-Dsqoop.version=<version> - default 1.4.3
+-Dsqoop.classifier=<classifier> - default hadoop100
+-jetty.version=<version> - default 9.3.20.v20170531
+-Dopenjpa.version=<version> - default 2.2.2
+-Dxerces.version=<version> - default 2.10.0
+-Dcurator.version=<version> - default 2.5.0
+-Dhive.version=<version> - default 1.2.0
+-Dhbase.version=<version> - default 1.2.3
+-Dtez.version=<version> - default 0.8.4
+```
+
+**IMPORTANT:** Profile hadoop-3 must be activated if building against Hadoop 3
+
+The following properties should be specified when building a release:
+
+ * -DgenerateDocs : forces the generation of Oozie documentation
+ * -Dbuild.time= : timestamps the distribution
+ * -Dvc.revision= : specifies the source control revision number of the distribution
+ * -Dvc.url= : specifies the source control URL of the distribution
+
+The provided `bin/mkdistro.sh` script runs the above Maven invocation setting all these properties to the
+right values (the 'vc.*' properties are obtained from the local git repository).
+
+## IDE Setup
+
+Eclipse and IntelliJ can use directly Oozie Maven project files.
+
+The only special consideration is that the following source directories from the `client` module must be added to
+the `core` module source path:
+
+ * `client/src/main/java` : as source directory
+ * `client/src/main/resources` : as source directory
+ * `client/src/test/java` : as test-source directory
+ * `client/src/test/resources` : as test-source directory

+# Creating Custom Authentication
+
+<!-- MACRO{toc|fromDepth=1|toDepth=4} -->
+
+## Hadoop-Auth Authentication Interfaces and classes
+
+1. `org.apache.hadoop.security.authentication.client.Authenticator:` Interface for client authentication mechanisms.
+
+ The following authenticators are provided in hadoop-auth:
+
+ * KerberosAuthenticator : the authenticator implements the Kerberos SPNEGO authentication sequence.
+ * PseudoAuthenticator : the authenticator implementation provides an authentication equivalent to Hadoop's Simple
+ authentication, it trusts the value of the 'user.name' Java System property.
+
+2. `org.apache.hadoop.security.authentication.server.AuthenticationHandler:` Interface for server authentication mechanisms.
+
+ * KerberosAuthenticationHandler : the authenticator handler implements the Kerberos SPNEGO authentication mechanism for HTTP.
+ * PseudoAuthenticationHandler : the authenticator handler provides a pseudo authentication mechanism that accepts the user
+ name specified as a query string parameter.
+
+3. `org.apache.hadoop.security.authentication.server.AuthenticationFilter:` A servlet filter enables protecting web application
+ resources with different authentication mechanisms provided by AuthenticationHandler. To enable the filter, web application
+ resources file (ex. web.xml) needs to include a filter class derived from `AuthenticationFilter`.
+
+ For more information have a look at the appropriate
+ [Hadoop documentation](https://hadoop.apache.org/docs/r2.7.2/hadoop-auth/index.html).
+
+## Provide Custom Authentication to Oozie Client
+
+Apache Oozie contains a default class `org.apache.oozie.client.AuthOozieClient` to support Kerberos HTTP SPNEGO authentication,
+pseudo/simple authentication and anonymous access for client connections.
+
+To provide other authentication mechanisms, an Oozie client should extend from `AuthOozieClient` and provide the following
+methods should be overridden by derived classes to provide custom authentication:
+
+ * getAuthenticator() : return corresponding Authenticator based on value specified by user at `auth` command option.
+ * createConnection() : create a singleton class at Authenticator to allow client set and get key-value configuration for
+ authentication.
+
+## Provide Custom Authentication to Oozie Server
+
+To accept custom authentication in Oozie server, a filter extends from AuthenticationFilter must be provided. This filter
+delegates to the configured authentication handler for authentication and once it obtains an `AuthenticationToken` from it, sets
+a signed HTTP cookie with the token. If HTTP cookie is provided with different key name, its cookie value can be retrieved by
+overriding `getToken()` method. Please note, only when `getToken()` return NULL, a custom authentication can be invoked and
+processed in `AuthenticationFilter.doFilter()`.
+
+The following method explains how to read it and return NULL token.
+
+```
+protected AuthenticationToken getToken(HttpServletRequest request) throws IOException, AuthenticationException {
+ String tokenStr = null;
+ Cookie[] cookies = request.getCookies();
+
+ if (cookies != null) {
+ for (Cookie cookie : cookies) {
+ if (cookie.getName().equals(AuthenticatedURL.AUTH_COOKIE)) {
+ tokenStr = cookie.getValue();
+ LOG.info("Got 'hadoop.auth' cookie from request = " + tokenStr);
+ if (tokenStr != null && !tokenStr.trim().isEmpty()) {
+ AuthenticationToken retToken = super.getToken(request);
+ return retToken;
+ }
+ } else if (cookie.getName().equals("NEWAUTH")) {
+ tokenStr = cookie.getValue();
+ // DO NOT return the token string so request can authenticated.
+ }
+ }
+ }
+ return null;
+ }
+```
