> Currently multiple customers are complaining on high services (re-)start time.
> From what we understood probably more than a minute is bad.
> So after discussion with Mahadev it was decided to move out beeline check
> which takes usually ~2 minutes (resulting in hive restarting in ~4minutes)
> from start to service check, which seems a good place for that.
> There is a problem due to Hive process asynchroniously starts and can drop
> start without Ambari knowing it.  
> Also this was implemented some time ago because of:
>     
>     
>     AMBARI-5800
>     Race condition when starting all services causing Hive service check to fail
>     
> But, since now service check does exactly the beeline check with mutiple
> retries this won't happen
> Test scenarios included:  
> 1\. Restart Hive and rt after it start service check  
> 2\. Restart Hive and rt after it restart Webhcat  
> 3\. Start service check with Hive Server HA
