Summary: [AMv2] CODE-BUG: Uncaught runtime exception for pid=....,
state=SUCCESS; AssignProcedure
Key: HBASE-20203
URL: https://issues.apache.org/jira/browse/HBASE-20203
Project: HBase
Issue Type: Bug
Components: amv2
Affects Versions: 2.0.0-beta-2
Reporter: stack
Assignee: stack
This is an odd one. Causes ITBLL to fail because region is offline.
Two seconds after reporting Finished, successful assign, another thread tries
to finish the Procedure. The second run messes us up.
