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