> Here's a case where TestReplicationDisableInactivePeer fails while re-starting the second
master:
> http://54.241.6.143/job/HBase-0.95-Hadoop-2/574/org.apache.hbase$hbase-server/testReport/junit/org.apache.hadoop.hbase.replication/TestReplicationDisableInactivePeer/testDisableInactivePeer/
> The reason is that when we first shutdown the master, it comes back to life thinking
it just lost its session:
> {noformat}
> 2013-07-07 04:27:03,989 FATAL [pool-1-thread-1-EventThread] master.HMaster(2062): Master
server abort: loaded coprocessors are: [org.apache.hadoop.hbase.coprocessor.MultiRowMutationEndpoint]
> 2013-07-07 04:27:03,989 INFO  [pool-1-thread-1-EventThread] master.HMaster(2155): Primary
Master trying to recover from ZooKeeper session expiry.
> {noformat}
> And after that it tries to assign .META. fails since the RS are down.
> One way I think we can prevent this is by skipping recovering the session if we are stopping.
