+Building
+=============
+basic compilation:
+> mvn clean compile test-compile
+
+Compile, run tests and produce jar
+> mvn clean package
+
+=============
+Unit tests
+=============
+Most of the tests will run without additional configuration.
+For complete testing, configuration in src/test/resources is required:
+ src/test/resources/azure-test.xml
+ src/test/resources/log4j.properties
+
+From command-line
+------------------
+Basic execution:
+> mvn test
+
+NOTES:
+ - The mvn pom.xml includes src/test/resources in the runtime classpath
+ - detailed output (such as log4j) appears in target\surefire-reports\TEST-{testName}.xml
+ including log4j messages.
+
+Run the tests and generate report:
+> mvn site (at least once to setup some basics including images for the report)
+> mvn surefire-report:report (run and produce report)
+> mvn mvn surefire-report:report-only (produce report from last run)
+> mvn mvn surefire-report:report-only -DshowSuccess=false (produce report from last run, only show errors)
+> .\target\site\surefire-report.html (view the report)
+
+Via eclipse
+-------------
+Manually add src\test\resources to the classpath for test run configuration:
+ - run menu|run configurations|{configuration}|classpath|User Entries|advanced|add folder
+
+Then run via junit test runner.
+NOTE:
+ - if you change log4.properties, rebuild the project to refresh the eclipse cache.
+
+Run Tests against Mocked storage.
+---------------------------------
+These run automatically and make use of an in-memory emulation of azure storage.
+
+
+Running tests against the Azure storage emulator
+---------------------------------------------------
+A selection of tests can run against the Azure Storage Emulator which is
+a high-fidelity emulation of live Azure Storage. The emulator is sufficient for high-confidence testing.
+The emulator is a Windows executable that runs on a local machine.
+
+To use the emulator, install Azure SDK 2.3 and start the storage emulator
+See http://msdn.microsoft.com/en-us/library/azure/hh403989.aspx
+
+Enable the Azure emulator tests by setting
+ fs.azure.test.emulator -> true
+in src\test\resources\azure-test.xml
+
+Running tests against live Azure storage
+-------------------------------------------------------------------------
+In order to run WASB unit tests against a live Azure Storage account, add credentials to
+src\test\resources\azure-test.xml. These settings augment the hadoop configuration object.
+
+For live tests, set the following in azure-test.xml:
+ 1. "fs.azure.test.account.name -> {azureStorageAccountName}
+ 2. "fs.azure.account.key.{AccountName} -> {fullStorageKey}"
+
+=============
+Findbugs
+=============
+Run findbugs and show interactive GUI for review of problems
+> mvn findbugs:gui
+
+Run findbugs and fail build if errors are found:
+> mvn findbugs:check
+
+For help with findbugs plugin.
+> mvn findbugs:help
+
+=============
+Checkstyle
+=============
+Rules for checkstyle @ src\config\checkstyle.xml
+ - these are based on a core set of standards, with exclusions for non-serious issues
+ - as a general plan it would be good to turn on more rules over time.
+ - Occasionally, run checkstyle with the default Sun rules by editing pom.xml.
+
+Command-line:
+> mvn checkstyle:check --> just test & fail build if violations found
+> mvn site checkstyle:checkstyle --> produce html report
+> . target\site\checkstyle.html --> view report.
+
+Eclipse:
+- add the checkstyle plugin: Help|Install, site=http://eclipse-cs.sf.net/update
+- window|preferences|checkstyle. Add src/config/checkstyle.xml. Set as default.
+- project|properties|create configurations as required, eg src/main/java -> src/config/checkstyle.xml
+
+NOTE:
+- After any change to the checkstyle rules xml, use window|preferences|checkstyle|{refresh}|OK

+===================================
+Page Blob Support and Configuration
+===================================
+
+The Azure Blob Storage interface for Hadoop supports two kinds of blobs, block blobs
+and page blobs. Block blobs are the default kind of blob and are good for most
+big-data use cases, like input data for Hive, Pig, analytical map-reduce jobs etc.
+Page blob handling in hadoop-azure was introduced to support HBase log files.
+Page blobs can be written any number of times, whereas block blobs can only be
+appended to 50,000 times before you run out of blocks and your writes will fail.
+That won't work for HBase logs, so page blob support was introduced to overcome
+this limitation.
+
+Page blobs can be used for other purposes beyond just HBase log files though.
+They support the Hadoop FileSystem interface. Page blobs can be up to 1TB in
+size, larger than the maximum 200GB size for block blobs.
+
+In order to have the files you create be page blobs, you must set the configuration
+variable fs.azure.page.blob.dir to a comma-separated list of folder names.
+E.g.
+
+ /hbase/WALs,/hbase/oldWALs,/data/mypageblobfiles
+
+You can set this to simply / to make all files page blobs.
+
+The configuration option fs.azure.page.blob.size is the default initial
+size for a page blob. It must be 128MB or greater, and no more than 1TB,
+specified as an integer number of bytes.
+
+====================
+Atomic Folder Rename
+====================
+
+Azure storage stores files as a flat key/value store without formal support
+for folders. The hadoop-azure file system layer simulates folders on top
+of Azure storage. By default, folder rename in the hadoop-azure file system
+layer is not atomic. That means that a failure during a folder rename
+could, for example, leave some folders in the original directory and
+some in the new one.
+
+HBase depends on atomic folder rename. Hence, a configuration setting was
+introduced called fs.azure.atomic.rename.dir that allows you to specify a
+comma-separated list of directories to receive special treatment so that
+folder rename is made atomic. The default value of this setting is just /hbase.
+Redo will be applied to finish a folder rename that fails. A file
+<folderName>-renamePending.json may appear temporarily and is the record of
+the intention of the rename operation, to allow redo in event of a failure.

+ * A blobUpload will generally involve concurrent upload worker threads that share one operationContext and one throttling instance.

+ * -- concurrent access to lastE2Edelay must be protected.
+ * -- volatile is necessary and should be sufficient to protect simple access to primitive values (java 1.5 onwards)
+ * -- synchronized{} blocks are also used to be conservative and for easier maintenance.
+ *
+ * If an operation were to perform concurrent GETs and PUTs there is the possibility of getting confused regarding
+ * whether lastE2Edelay was a read or write measurement. This scenario does not occur.
+ *
+ * readFactor = target read throughput as factor of unrestricted throughput.
+ * writeFactor = target write throughput as factor of unrestricted throughput.
