HCM.locateRootRegion fails hard on "Connection refused"
-------------------------------------------------------
Key: HBASE-2417
URL: https://issues.apache.org/jira/browse/HBASE-2417
Project: Hadoop HBase
Issue Type: Bug
Affects Versions: 0.20.3
Reporter: Jean-Daniel Cryans
Fix For: 0.20.4, 0.21.0
While running some tests on replication, I saw that our client does something
dumb if it tries to contact a dead region server that held the ROOT region in
HCM.locateRootRegion. Will post stack trace in a comment.
The problem here is that we don't retry at all, the exception will come
straight out of HCM like it's the end of the world.
