Summary: Inconsistencies in verifying Max Applications
Key: YARN-6157
URL: https://issues.apache.org/jira/browse/YARN-6157
Project: Hadoop YARN
Issue Type: Bug
Reporter: Naganarasimha G R
Inconsistencies in verifying Max Applications when the max apps is reduced and
either HA is done ow work preserving restart is done.
# currently Max applications across cluster should not be done for the
recovered apps. Seems like currently we are doing it
# Max applications for a queue is done @ CapacityScheduler.addApplication
which considers sum of Pending and running applications but we add to pending
applications in {{CapacityScheduler.addApplicationAttempt ->
LeafQueue.addApplicationAttempt}} so between these 2 checks we can activate
more apps than what can queue restrict.
# During recovery of a RMApp, if applicationAttempts are not found then we
recover it without recovery false @ {{RMAppImpl.RMAppRecoveredTransition}},
this can lead to failure of apps which were accepted earlier but attempt was
not yet created and HA happens when MAX app configuration (for cluster/queue)
is modified.
