---------------------------------
Hi [~hex108], It is a good catch. Java doesn't allow overriding of static
methods. That is why getVersion always get the version of hadoop common.
> Fix components' version information in the web page 'About the Cluster'

> In the web page 'About the Cluster', YARN's component's build version(e.g.
> ResourceManager) is the same as Hadoop version now. It is caused by calling
> getVersion() instead of _getVersion() in VersionInfo.java by mistake.
