----------------------------------
Summary: NPE in MoveRegionProcedure via
IntegrationTestLoadAndVerify with CM
Key: HBASE-20131
URL: https://issues.apache.org/jira/browse/HBASE-20131
Project: HBase
Issue Type: Bug
Components: proc-v2
Reporter: Josh Elser
Assignee: Josh Elser
Fix For: 2.0.0
I believe the error is that a MoveRegionProcedure comes in via ChaosMonkey for
an unassigned region that was from a disabled table (also due to CM) which
causes an NPE as we try to set a null original location into the protobuf which
fails.

IntegrationTestLoadAndVerify also failed, but I'm not sure if it's related to
this, or just a problem with the test. The test failed because the table was
left offline after it was disabled, and appears to not have been re-enabled.
Still debugging that side..
