------------------------------------
Summary: Yarn scheduler changes should not prompt Resource Manager
restarts now that Scheduler Refresh is available
Key: AMBARI-10833
URL: https://issues.apache.org/jira/browse/AMBARI-10833
Project: Ambari
Issue Type: Improvement
Components: ambari-server
Affects Versions: 2.0.0
Environment: HDP 2.2
Reporter: Hari Sekhon
Priority: Trivial
Ambari has had Yarn Scheducler Refresh capability for a little while now since
1.7 (AMBARI-5937) but it still prompts users to restart Yarn Resource Managers
which is unnecessary.
It should instead prompt users via the message above config to run a Scheduler
Refresh. After a Scheduler Refresh the prompt for restarting the Resource
Managers goes away, but less experienced users could end up often needlessly
rebooting their Resource Managers due to this message.
