---------------------------------------
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.
