Tao Yang commented on YARN-9664:
--------------------------------
Attached v1 patch for review.
Updates:
* Adjust structure and diagnostics for the response of activities
** Refactor activity diagnostics to make them more sensible: begin with
activity level and adjust some contents
** Refactor field names: allocationState -> activityState, requestAllocation ->
requestAllocations, allocationAttempt -> allocationAttempts
** Adjust the sequence of some fields
** Correct unreasonable activity states
** Add activity diagnostics for initial check at the beginning of scheduling
process
* Support recording and showing partition name in scheduler activities
* Add activity level including QUEUE/APP/REQUEST/NODE and improve the recording
process to get better classifications
* UT
** Add new test cases (testQueueSkippedBecauseOfHeadroom and
testNodeSkippedBecauseOfRelaxLocality) in TestRMWebServicesSchedulerActivities
to test diagnostics at request/node level
** Add testPartitionInSchedulerActivities in
TestRMWebServicesForCSWithPartitions to test partition information
** Update frequently-used strings to be constants
> Improve response of scheduler/app activities for better understanding

> Currently some diagnostics are not easy enough to understand for common
> users, and I found some places still need to be improved such as no partition
> information and lacking of necessary activities. This issue is to improve
> these shortcomings.
