Harsh J commented on HBASE-6071:
--------------------------------
Nice patch. I'd prefer if we logged this at INFO itself though. This sorta
retry is also known to kill remote bulkloads with tons of re-requests presently
and we wouldn't know that if we didn't catch it via logs.
Secondly, it is tough on many older versions of Hadoop to enable DEBUG level
logs in MR (where this (LE) is often reported from).
> getRegionServerWithRetires, should log unsuccessful attempts and exceptions.
