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.
