Committed on 0.95 & trunk. I don't know why it doesn't show up on the 0.94.
Thanks for the finding, the tests and the review JD!. Thanks for the review Stack.

> I killed -STOP a region server and let it stay like that while running PE. The clients
didn't find the new region locations and in the jstack were stuck doing RPC. Eventually I
killed -CONT and the client printed these:
> bq. Exception in thread "TestClient-6" java.lang.RuntimeException: org.apache.hadoop.hbase.client.RetriesExhaustedWithDetailsException:
