Bikas Saha commented on YARN-231:
---------------------------------
No. I mean RMStateStoreImpl catching store exceptions and figuring out whether
master status has been lost or its an unrelated store error. e.g. An error
saying the store has disallowed access vs and error saying the store is
unavailable. The first would be an HA exception meaning the RM should stop vs
the second exception would mean a loss of store which may be tolerable when
storing non-critical information like node health. So, I would like to narrow
down from Exception into a better subset as we progress instead of making
everything look like an IOException now.
Good point. I will mark stuff as Unstable instead for both this and YARN-230
