----------------------------------
Summary: Fully enable ServerShutdownHandler after master joins the
cluster
Key: HBASE-6483
URL: https://issues.apache.org/jira/browse/HBASE-6483
Project: HBase
Issue Type: Sub-task
Reporter: Jimmy Xiang
Once ROOT and META are assigned, ServerShutdownHandler is enabled. So that we
can handle meta/root region server failure before joinCluster is completed.
However, we can hold ServerShutdownHandler a little bit more for the user
region assignments, i.e. doesn't assign user regions before joinCluster is
returned. If so, we can avoid some region assignments racing: same regions are
trying to be assigned in both joinCluster and ServerShutdownHandler.
