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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
