Jian He commented on YARN-2865:
-------------------------------
patch looks good overall.
The patch should be enough to fix this jira. In addition, we need to clear
"systemCredentials, schedulerRecoveryStartTime, schedulerRecoveryWaitTime etc..
" too.. probably we should have a separate class including all the active
services' context and instantiate a new class when transitioning from standby
to active for future-proof, instead of reseting each individual field.
thoughts? we can definitely do this separately
> Application recovery continuously fails with "Application with id already
> present. Cannot duplicate"

> YARN-2588 handles exception thrown while transitioningToActive and reset
> activeServices. But it misses out clearing RMcontext apps/nodes details and
> ClusterMetrics and QueueMetrics. This causes application recovery to fail.
