Andrew Purtell commented on HBASE-932:
--------------------------------------
Reconsider HRS restart strategy as part of handling transient filesystem
problems. Should happen only after trying a "safe mode" first, as part of a
ride over HDFS restart capability. If can't leave safe mode after some
configured interval elapses, then consider how to shut down.
Can't shut down if unfinished writes to WAL are still pending.

> If we drop a flush or we fail close a write-ahead log, we currently shutdown
> the regionserver (we fail because of hdfs usually). Rather than shut
> themselves down, how about they restart? The restart at least in the
> HBASE-930 might fix the issue shaking DFSClient so it gets sense again. Even
> is HDFS is bad, it'll come around eventually. The HRS restarting itself plus
> HBASE-926 fix will make for fast recovery.
