----------------------------------------
Summary: Move hiveserver2 beeline check to Hive SC and do mupliple
other service-level optimizations
Key: AMBARI-11271
URL: https://issues.apache.org/jira/browse/AMBARI-11271
Project: Ambari
Issue Type: Bug
Reporter: Andrew Onischuk
Assignee: Andrew Onischuk
Fix For: 2.1.0
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
