Yusaku Sako updated AMBARI-19720:
---------------------------------
Resolution: Fixed
Status: Resolved (was: Patch Available)
> when restarting HSI, Ambari should not run slider stop and slider destroy
> (LLAP script already does that)
> ---------------------------------------------------------------------------------------------------------
>
> Key: AMBARI-19720
> URL: https://issues.apache.org/jira/browse/AMBARI-19720
> Project: Ambari
> Issue Type: Bug
> Components: stacks
> Affects Versions: 2.5.0
> Reporter: Sumit Mohanty
> Assignee: Sumit Mohanty
> Priority: Critical
> Fix For: 2.5.0
>
>
> These commands are pure overhead, because spinning up slider and connecting
> to things is slow. On some test cluster it took ~12sec to do 100ms of noop
> work.
> LLAP script already runs them and will eventually avoid the overhead by
> calling Slider APIs from an existing JVM. However we just noticed when
> restarting HSI (but not when restarting LLAP only), Ambari also runs these
> commands.
