> It's an issue when to run "bin/hbase master stop" to shutdown the cluster.
> This could be reproduced by the following steps. Particularly for the trunk
> code, we need to configure the hbase.assignment.maximum.attempts as 1.
> 1. Start one master and several region servers.
> 2. Stop all the region servers.
> 3. After a while, run "bin/hbase master stop" to shutdown the cluster.
> As a result, the master could not be stopped within a short time, but will
> be stopped after several hours. And after it's stopped, i find the error logs.
> 1. For the trunk:
> A. lots of the logs which are "java.io.IOException: Failed to find
> location, tableName=hbase:meta, row=, reload=true"
> B..And at last, there's one exception before the master is stopped,
> "ServerShutdownHandler: Received exception accessing hbase:meta during server
> shutdown of server-XXX, retrying hbase:meta read
> java.io.InterruptedIOException: Interrupted after 0 tries on 350."
> 2. For the branch 0.94:
> A. lots of the logs which are "Looked up root region location,
> connection=org.apache.hadoop.hbase.client.HConnectionManager$HConnectionImplementation@44285d14;
> serverName=".
> B. And at last, there's one exception before the master is stopped,
> "ServerShutdownHandler: Received exception accessing META during server
> shutdown of server-XXX, retrying META read
> org.apache.hadoop.hbase.client.NoServerForRegionException: Unable to find
> region for after 140 tries."
> We could see the master are stopped after lots of reties which are not
> necessary when the cluster is shutdown.
