-----------------------------------------
looks pretty good, just needs some final tuning
* typo "configuraion" in docs.
* checkstyle has found 3 minor issues, which we need to get in

> WASB passes a User-Agent header to the Azure back-end. Right now, it uses the
> default value set by the Azure Client SDK, so Hadoop traffic doesn't appear
> any different from general Blob traffic. If we customize the User-Agent
> header, then it will enable better troubleshooting and analysis by Azure
> service.
> The following configuration
> <property>
> <name>fs.azure.user.agent.id</name>
> <value>MSFT</value>
> </property>
> set the user agent to
> User-Agent: WASB/3.0.0-alpha4-SNAPSHOT (MSFT) Azure-Storage/4.2.0
> (JavaJRE 1.8.0_131; WindowsServer2012R2 6.3)
> Test Results :
> Tests run: 703, Failures: 0, Errors: 0, Skipped: 119
