[jira] [Created] (HBASE-21508) Ignore the reportRegionStateTransition call from a dead server

Duo Zhang created HBASE-21508:
---------------------------------

             Summary: Ignore the reportRegionStateTransition call from a dead server
                 Key: HBASE-21508
                 URL: https://issues.apache.org/jira/browse/HBASE-21508
             Project: HBase
          Issue Type: Sub-task
          Components: amv2
            Reporter: Duo Zhang
             Fix For: 3.0.0, 2.2.0


In our ITBLL test we observer a race between the SCP and TRSP which causes a region being assigned to two region servers.

Not fully understand the scenario, but anyway, the we do not consider the situation in the old code, that after SCP gets the region list of a dead server, there could still be a reportRegionStateTransition call from dead server and mess up things.

In general, I think we should have a fence in the AssignmentManager to prevent the reportRegionStateTransition from the dead servers to mess up the states.
