Sumit Mohanty created AMBARI-19720:
--------------------------------------
Summary: 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.
