--------------------------------------

Is that related to (or the same as) HBASE-7521?

> Visiting a user today, I came across following interesting case (0.94.2 HBase).
> A server was added to cluster.  It was assigned regions by the balancer.  A bunch opened
on the regionserver and just after the open, the regionserver was manually shutdown.  There
was a lag processing the zk region open events in the master (because clean shutdown, there
was no zk activity when the regions were closed on the shutdown regionserver).  Processing
the server shutdown, we do this for a good few of the regions that had just been opened on
the regionserver:
> 2013-01-30 02:41:19,917 INFO org.apache.hadoop.hbase.master.handler.ServerShutdownHandler:
Skip assigning region OBFUSCATED_TABLE,OBFUSCATED_STARTROW,1344723216908.55e9cb551edeea0b52bb91af7c2de199.
state=OPEN, ts=1359513674715, server=XX.XX.18.40,10304,1359513445136
> Seems like outright bug that'd we'd skip a region that is in transition that is in the
OPEN state.
> More detail to follow.
