Yufei Gu commented on YARN-6112:
--------------------------------
Patch 003:
Remove the updateCall metrics and related measurement in function {{update}}
since it is identical to updateThreadRun right now. We'll keep it in branch-2
as [~kasha] suggested.
> fsOpDurations.addUpdateCallDuration() should be independent to LOG level

> In the update thread of Fair Scheduler, the
> {{fsOpDurations.addUpdateCallDuration()}} records the duration of
> {{update()}}, it should be independent to LOG level. YARN-4752 put the it
> inside a {{LOG.isDebugEnabled()}} block. Not sure any particular reason to do
