Phabricator commented on HBASE-5813:
------------------------------------

mbautin has commented on the revision "[jira] [HBASE-5813] [89-fb] Retry immediately after a NotServingRegionException in a multiput".

  All unit tests passed. I also ran Test*ServerCmdLine tests from D2811 and checked the logs for retries after a NotServingRegionException. This fix did save two five-second pauses in those tests.

> After we get some errors in a multiput we invalidate the region location cache and wait for the configured time interval according to the backoff policy. However, if all "errors" in multiput processing were NotServingRegionExceptions, we don't really need to wait. We can retry immediately.
