Put hangs for 10 retries on failed region servers
-------------------------------------------------

                 Key: HBASE-2421
                 URL: https://issues.apache.org/jira/browse/HBASE-2421
             Project: Hadoop HBase
          Issue Type: Bug
            Reporter: Jean-Daniel Cryans
            Assignee: ryan rawson
            Priority: Critical
             Fix For: 0.20.5, 0.21.0


Since MultiPut got in, instead of calling getRegionLocationForRowWithRetries we now call getRegionServerWithRetries
to send an array list of Puts. The problem is that if the region server failed, we'll still
retry the 10 times in a backoff fashion even tho we get connections refused. This is also
true for a single put since it's the same code path.

Marking as critical since it almost disables our responsiveness to machine failures in certain
cases where we are already sending a batch of edits when the server fails. Assigning to Ryan
since he's been there recently.
