>
> org.apache.hadoop.util.VersionInfo is commonly used by applications that work
> with multiple versions of Hadoop.
> In case of Hive, this is used in a shims layer to identify the version of
> hadoop and use different shim code based on version (and the corresponding
> api it supports).
> I checked Pig and Hbase as well and they also use this class to get version
> information.
> However, this method is annotated as "@private" and "@unstable".
> This code has actually been stable for long time and is widely used like a
> public api. I think we should mark it as such.
> Note that there are apis to find the version of server components in hadoop,
> however, this class necessary for finding the version of client.
