which is only set on downgrade.

> 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.
