Sergey Shelukhin created HBASE-7268:
---------------------------------------

             Summary: correct local region location cache information can be overwritten w/stale
information from an old server
                 Key: HBASE-7268
                 URL: https://issues.apache.org/jira/browse/HBASE-7268
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.96.0
            Reporter: Sergey Shelukhin
            Assignee: Sergey Shelukhin
            Priority: Minor


Discovered via HBASE-7250; related to HBASE-5877.
Test is writing from multiple threads.
Server A has region R.
R gets moved from A to server B.
Server B gets killed.
Region gets moved by master to server C.
~15 seconds later, client tries to write to it.
Multiple client threads report "region moved from C to B", even though such transition never
happened (neither in nor before the sequence described below).

I have a patch but not sure if it works, test still fails locally for yet unknown reason.
