Chris Trezzo commented on YARN-5009:
------------------------------------

Adding 2.6.5 to the target versions with the intention of backporting this to branch-2.6.
Please let me know if you think otherwise. Thanks!

> Similar to the RM case in YARN-5008, I have seen state stores for nodemanagers with high
container churn become significantly larger than they should be due to lack of sufficient
database compaction.
