Sergey Shelukhin commented on HBASE-21577:
------------------------------------------
The issue happens mostly with other regions, DroppedSnapshot almost always
indicates some filesystem issue. As other regions are closing, they go thru the
retries in various places.
[~Apache9] does the patch look good to you after update?
> do not close regions when RS is dying due to a broken WAL

> See HBASE-21576. DroppedSnapshot can be an FS failure; also, when WAL is
> broken, some regions whose flushes are already in flight keep retrying,
> resulting in minutes-long shutdown times. Since WAL will be replayed anyway
> flushing regions doesn't provide much benefit.
