-----------------------------------
Summary: Assignments are not retained on a cluster start
Key: HBASE-10333
URL: https://issues.apache.org/jira/browse/HBASE-10333
Project: HBase
Issue Type: Bug
Reporter: Devaraj Das
When a cluster is fully shutdown and then started up again with
hbase.master.startup.retainassign set to true, I noticed that the assignments
are not retained. Upon digging, it seems like HBASE-10101 made a change due to
which the server holding the META previously is added to dead-servers (in
_HMaster.assignMeta_). Later on, this makes the AssignmentManager think that
the master recovered from a failure as opposed to a fresh cluster start (the
ServerManager.deadServers list is not empty in the check within
_AssignmentManager.processDeadServersAndRegionsInTransition_)
