+# Hadoop Authentication Service (HAS)
+A dedicated Hadoop Authentication Server to support various authentication mechanisms other than just Kerberos. In its core it leverages a Kerby KDC developed by [Apache Kerby](https://github.com/apache/directory-kerby), a sub project of [Apache Directory](http://directory.apache.org).
+
+# High level considerations
+* Hadoop services are still strongly authenticated by Kerberos, as Kerberos is the only means so far to enable Hadoop security.
+* Hadoop users can remain to use their familiar login methods.
+* Security admins won't have to migrate and sync up their user accounts to Kerberos back and forth.
+* New authentication mechanism can be customized and plugined.
+
+# Architecture
+
+
+# Design
+Assuming existing users are stored in a SQL database (like MySQL), the detailed design and workflow may go like the following:
+
+
+
+# New mechanism plugin API
+
+## HAS client plugin HasClientPlugin:
+
+```Java
+// Get the login module type ID, used to distinguish this module from others.
+// Should correspond to the server side module.
+String getLoginType()
+
+// Perform all the client side login logics, the results wrapped in an AuthToken,
+// will be validated by HAS server.
+AuthToken login(Conf loginConf) throws HasLoginException
+```
+
+## HAS server plugin HasServerPlugin:
+
+```Java
+// Get the login module type ID, used to distinguish this module from others.
+// Should correspond to the client side module.
+String getLoginType()
+
+// Perform all the server side authentication logics, the results wrapped in an AuthToken,
+// will be used to exchange a Kerberos ticket.
+AuthToken authenticate(AuthToken userToken) throws HasAuthenException
+```

+Establish cross realm trust
+============
+
+### Synchronize time of realms
+The time of realms should be synchronized.
+
+### Add the same special principals in realms, please select a very strong password
+```
+cd kerby-dist/kdc-dist
+sh bin/kadmin.sh [server-conf-dir] -k [keytab]
+// A.EXAMPLE.COM realm to access a service in the B.EXAMPLE.COM realm
+HadminLocalTool.local: addprinc -pw [same-password] krbtgt/B.EXAMPLE.COM@A.EXAMPLE.COM
+// Make sure that both principals have matching key version numbers and encryption types
+HadminLocalTool.local: getprinc krbtgt/B.EXAMPLE.COM@A.EXAMPLE.COM
+```
+
+### Configure krb5.conf of realms
+
+* config realms and domain_realms sections, make sure the realms are contained.
+
+* config capaths section, which contains the realm chain.
+
+An example of krb5.conf:
+```
+[realms]
+ A.EXAMPLE.COM = {
+ kdc = A.EXAMPLE.COM
+ }
+ B.EXAMPLE.COM = {
+ kdc = B.EXAMPLE.COM
+ }
+
+[domain_realm]
+ .A.EXAMPLE.COM = a.example.com

+ A.EXAMPLE.COM = {
+ B.EXAMPLE.COM = .
+ }
+ B.EXAMPLE.COM = {
+ A.EXAMPLE.COM = .
+ }
+```
+
+> Make sure the FQDN match the realm name, e.g. if the FQDN is localhost.hadoop.com, the realm should be HADOOP.COM.
+
+### Validate
+```
+cd kerby-dist/tool-dist
+sh bin/kinit.sh -conf [client-conf-dir] -c [credential-cache-of-local-realm] -S [principal-name-of-remote-realm]

+Deploy HTTPS
+===============
+
+## 1. Create a keystore file for each host
+
+> keystore: the keystore file that stores the certificate.
+> validity: the valid time of the certificate in days.
+```
+keytool -alias {hostname} -keystore {keystore} -validity {validity} -genkey
+```
+
+> The keytool will ask for more details such as the keystore password, keypassword and CN(hostname).
+
+## 2. Export the certificate public key to a certificate file for each host
+```
+keytool -export -alias {hostname} -keystore {keystore} -rfc -file {cert-file}
+```
+
+## 3. Create a common truststore file (trustAll)
+The truststore file contains the public key from all certificates. If you assume a 2-node cluster with node1 and node2,
+login to node1 and import the truststore file for node1.
+```
+keytool -import -alias {hostname} -keystore {trustAll} -file {cert-file}
+```
+
+## 4. Update the common truststore file
+* Move {trustAll} from node1 to node2 ({trustAll} already has the certificate entry of node1), and repeat Step 3.
+
+* Move the updated {trustAll} from node2 to node1. Repeat these steps for each node in the cluster.
+When you finish, the {trustAll} file will have the certificates from all nodes.
+
+> Note these work could be done on the same node, just notice the hostname.
+
+## 5. Copy {trustAll} from node1 to all of the other nodes
+
+## 6. Validate the common truststore file
+```
+keytool -list -v -keystore {trustAll}

+Deploy SPNEGO
+================
+
+## 1. Server Side Configuration(in server side has-server.conf)
+
+To use Kerberos SPNEGO as the authentication mechanism, the authentication filter must be configured with the following init parameters:
+- filter_auth_type : the keyword kerberos. For example: filter_auth_type = kerberos
+
+## 2. Client Side Configuration(in client side hadmin.conf)
+
+- filter_auth_type the keyword kerberos. For example: filter_auth_type = kerberos
+- admin_keytab: The path to the keytab file containning the credential for the admin principal. For example: admin_keytab = /etc/has/admin.keytab Here the admin.keytab the same as the server side.
+- admin_keytab_principal: The admin principal. For example: admin_keytab_principal = kadmin/<YOUR-REALM.COM>@<YOUR-REALM.COM>

+High Availability Using MySQL Backend
+========================================
+
+The HAS High Availability feature implemented by providing the option of running two redundant HAS servers.
+
+## Deployment
+
+### 1. Configure has-server.conf
+
+The two redundant HAS servers must have same https ports. Below are examples:
+
+* has-server.conf of HAS server on emr-header-1:
+```
+[HAS]
+ https_host = emr-header-1
+ https_port = 8092
+ filter_auth_type = kerberos
+ enable_conf = true
+
+[PLUGIN]
+ auth_type = RAM
+```
+
+* has-server.conf of HAS server on emr-worker-1:
+```
+[HAS]
+ https_host = emr-worker-1
+ https_port = 8092
+ filter_auth_type = kerberos
+ enable_conf = true
+
+[PLUGIN]
+ auth_type = RAM
+```
+
+### 2. Start HAS servers
+
+### 3. Configure HAS backend
+
+The two redundant HAS servers must use **mysql** backend, and have same *mysql_url*, *mysql_user* and *mysql_password*.
+
+Please look at [How to use mysql backend](https://github.com/intel-bigdata/has/blob/release-1.0.0/doc/mysql-backend.md) for mysql backend configuration.
+
+### 4. Configure HAS KDC
+
+The two redundant HAS servers must have same ports and realms.
+
+### 5. Start and init HAS KDC servers
+
+> After doing init on either HAS server, the other one has been initialized too.
+>
+> Please keep the shared admin.keytab safely.
+
+### 6. Reexport has-client.conf for HAS web server HA
+
+```
+cd HAS/has-dist
+// Start KDC init tool
+sh bin/kdcinit.sh <conf_dir>
+// Get has-client.conf, and put it to /etc/has:
+KdcInitTool: gethas -p /etc/has
+KdcInitTool: exit
+```
+
+You will get has-client.conf like the following:
+```
+[HAS]
+ https_host = emr-header-1,emr-worker-1
+ https_port = 8092
+ filter_auth_type = kerberos
+ enable_conf = true
+
+[PLUGIN]
+ auth_type = RAM
+```
+
+Hadoop user can use HAS HA feature by updating **core-site.xml** without Reexport has-client.conf.
+add the following properties:
+```
+<property>
+ <name>hadoop.security.has</name>
+ <value>https://emr-header-1:8092/has/v1?auth_type=RAM;https://emr-worker-1:8092/has/v1?auth_type=RAM</value>
+</property>
+```
+
+### 7. Reexport krb5.conf for HAS KDC HA
+
+```
+cd HAS/has-dist
+// Start KDC init tool:
+sh bin/kdcinit.sh <conf_dir>
+// Get krb5.conf, and put it to /etc:
+KdcInitTool: getkrb5 -p /etc
+KdcInitTool: exit
+```
+
+You will get krb5.conf like the following:
+```
+[libdefaults]
+ kdc_realm = HADOOP.COM
+ default_realm = HADOOP.COM
+ udp_preference_limit = 4096
+ kdc_tcp_port = 88
+ kdc_udp_port = 88
+
+[realms]
+ HADOOP.COM = {
+ kdc = localhost:88
+ kdc = localhost:88
+ }
+```
+
+## Verification
+
+You can use login-test tool to verify:
+
+### 1. Update hadmin.conf in <conf_dir>
+
+### 2. Run login-test tool
+```
+cd HAS/has-dist
+// Use tgt to login
+sh bin/login-test.sh tgt <conf_dir>
+```

+Please restart the HAS server
+
+```
+cd HAS/has-dist
+sh bin/stop-has.sh
+
+cd HAS/has-dist
+sh bin/start-has.sh <conf_dir> <work_dir>
+
+cd HAS/has-dist
+sh bin/kdcinit.sh <conf_dir>
+KdcInitTool: start
+KdcInitTool: exit
+```
+
+### Get krb5.conf:
+```
+cd HAS/has-dist
+// Start KDC init tool:
+sh bin/kdcinit.sh <conf_dir>
+// Get krb5.conf, and put it to /etc:
+KdcInitTool: getkrb5 -p /etc
+KdcInitTool: exit
+```
+
+### Get has-client.conf:
+```
+cd HAS/has-dist
+// Start KDC init tool
+sh bin/kdcinit.sh <conf_dir>
+// Get has-client.conf, and put it to /etc/has:
+KdcInitTool: gethas -p /etc/has
+KdcInitTool: exit
+```
+
+## 3. Prepare for Hadoop
+
+### Create service principals:
+```
+cd HAS/has-dist
+echo { \
+ HOSTS: [ \
+ {"name":"<host>","hostRoles":"<role>,..., <role>"\}, \
+ ...
+ {"name":"<host>","hostRoles":"<role>,...,<role>"\} \
+ ] \
+\} > hosts.txt
+// Start local hadmin tool
+sh bin/hadmin-local.sh <conf_dir> -k <keytab>
+// Also: sh bin/hadmin-local.sh -k <keytab>, if HAS_CONF_DIR environment variable has been set.
+// Also you can use remote hadmin tool, admin.keytab file needed to be placed in /etc/has
+sh bin/hadmin-remote.sh <conf_dir>
+// Also: sh bin/hadmin-remote.sh, if HAS_CONF_DIR environment variable has been set.
+HadminLocalTool.local: creprincs hosts.txt
+HadminLocalTool.local: exit
+```
+The admin.keytab file is created by the kdcinit. In local and remote hadmin tool, you can type "?" for help.
+
+### Get hostRoles list:
+```
+cd HAS/has-dist
+// Start local or remote hadmin tool
+sh bin/hadmin-local.sh(bin/hadmin-remote.sh) <conf_dir> -k <keytab>
+HadminLocalTool.local: hostroles
+HadminLocalTool.local: exit
+```
+
+### Export service keytabs:
+```
+cd HAS/has-dist
+// Start local or remote hadmin tool
+sh bin/hadmin-local.sh(bin/hadmin-remote.sh) <conf_dir> -k <keytab>
+// An example of exporting keytabs of localhost(hostname):
+HadminLocalTool.local: expkeytabs localhost
+HadminLocalTool.local: exit
+```

+# HAS Performance Test Report
+
+## 1. Overview
+
+HAS is a dedicated Hadoop authentication server to support various authentication mechanisms other than just Kerberos. With HAS users can remain their familiar login methods, and new authentication mechanism could be customized and plugined.
+
+A Hadoop cluster could have thousands of nodes, there maybe so many authentication requests are sent to HAS server at the same time. So the stability in high concurrency is so important for HAS.
+
+## 2. Test Environment
+
+The test use Alibaba Cloud Elastic Compute Service, detailed test environment like the following:
+
+### 2.1 Hardware environment
+
+* HAS Server:
+
+> CPU：Intel(R) Xeon(R)CPU E5-2682 @ 2.50GHz
+> MEM: 16GB
+> Disk: 43GB 86GB
+
+* HAS Client:
+
+> CPU：Intel(R) Xeon(R)CPU E5-2682 @ 2.50GHz
+> MEM: 16GB
+> Disk: 43GB 86GB * 3
+
+### 2.2 Software environment
+
+> OS: CentOS 7.2
+> JAVA: 1.8
+> HAS: 1.0.0
+> MySQL: 5.5.52
+
+## 3. Test Method
+
+By using [login-test](https://github.com/Intel-bigdata/HAS/blob/master/has-dist/bin/login-test.sh) scripting tool, the test can be broadly divided into four steps:
+
+1. Add principals to HAS server
+2. Export keytab files to HAS Client
+
+ ```shell
+ cd HAS/has-dist
+ sh bin/login-test add <conf_dir> <work_dir> <principal_num>
+ ```
+
+3. Use keytab files to login concurrently
+
+ ```shell
+ sh bin/login-test run <conf_dir> <work_dir> <concurrency_num>
+ ```
+
+4. Record login result and the cost time of login
+
+Testing process like the following:
+
+
+
+## 4. Test Result
+
+The test result consists of total cost time and time per request of login using keytab file.
+
+### 4.1 Using Json Backend
+
+| Concurrency | 100 | 500 | 1000 | 5000 | 8000 | 10000 |
+| :---: | :---: | :---: | :---: | :---: | :---: | :---: |
+| Result | Success | Success | Success | Success | Success | Success |
+| Total time (ms) | 540 | 1115 | 1661 | 4571 | 6328 | 7208 |
+| Time per request (ms)| 5.400 | 2.230 | 1.661 | 0.914 | 0.791 | 0.721 |
+
+### 4.2 Using MySQL Backend
+
+MySQL Configuration：
+> max connection: 5000
+> innodb buffer size: 8G
+
+| Concurrency | 100 | 500 | 1000 | 5000 | 8000 | 10000 |
+| :---: | :---: | :---: | :---: | :---: | :---: | :---: |
+| Result | Success | Success | Success | Success | Success | Success |
+| Total time (ms) | 765 | 2880 | 4821 | 12712 | 21419 | 22968 |
+| Time per request (ms)| 7.650 | 5.760 | 4.821 | 2.542 | 2.677 | 2.297 |
+
+## 5. Conclusion
+
+
+
+Figure above demonstrates the time per request of HAS authentication in different backends and concurrency. As can be seen, HAS can complete authentication work in high concurrency, and has a good performance. So HAS is good enough for Hadoop.
+
+The CPU utilization and network IO of HAS server are demonstrated in the appendix, with the number of concurrency up to 10000. The appendix shows that HAS server is not under heavy workload in mysql backend.
