My HBase cluster just crashed. One of the Region servers stopped (do not yet
know why). After restarting it, the cluster seemed a but wobbly, so I decided
to shutdown everything, and restart fresh. I did so (including zookeeper and
HDFS).
Upon restart, I'm getting the following message in the Master's log file
repeating continuously with the number of ms waited counting up.

The region servers are waiting with this being the final message in their log
file:

org.apache.hadoop.hbase.regionserver.HRegionServer: Telling master at
10.104.37.247:60000 that we are up
I've been using this version for a little under a week without incident
(http://people.apache.org/~jdcryans/hbase-0.89.20100830-candidate-1/ ).
The HDFS comes from CDH3.
Does anybody have any ideas on what I can do to get back up and running?
Thank you,
Matthew
