> During upgrade/downgrade, the deregister is happening before the new HS2 is started.
This can lead to a case where there is no HS2 up and running. The order needs to be fixed,
to first start target version of HS2 and then do the deregister.
> 1. Switch hive-server2 to the new software version, start the new process, and deregister
the old version of hive-server2:
> Since the current version would have changed before hive version is obtained for deregister
command, the version should be obtained using the HDP versioned path.
> /usr/hdp/$HDP_VERSION/hive/bin/hive --version 
> It will be safer to use the full path to hive for this, instead of relying on the $PATH
variable setting.
