---------------------------------
Summary: The shutdown of master will hang if there are no live
region server
Key: HBASE-20144
URL: https://issues.apache.org/jira/browse/HBASE-20144
Project: HBase
Issue Type: Bug
Reporter: Duo Zhang
In a graceful shutdown, we will set cluster down in ServerManager, and in
ServerManger.expireServer, if the cluster down flag is true and all rses are
gone, we will call master.stop and quit.
But if we have no live rs when shutting down, then expireServer will never be
triggered, so we are dead...
