Jason Lowe updated YARN-5009:

Nice catch!  Yes, it should be using a long to avoid overflow in case someone wants to configure
a cycle that's on the order of months.  I updated the patch accordingly.

> 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.
