Jason Lowe commented on YARN-5009:
----------------------------------

Thanks for the review and commit, Jian!  Note that the commit to branch-2.7 had 
a bad conflict resolution in yarn-default.xml, so I reverted and recommitted to 
correct it.

> NMLeveldbStateStoreService database can grow substantially leading to longer 
> recovery times

> 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.
