Re: HBase looses regions.

Go to the hosts where you think you run DataNodes and check what is set 
for "HADOOP_LOG_DIR" in
    $HADOOP_HOME/conf/hadoop-env.sh
(It is "$HADOOP_HOME/logs" by default.)
If there is no log like
    "$HADOOP_LOG_DIR/hadoop-user-datanode-hostname.log"
in that dir I'd assume you are not running DataNode on that host.

Where is the datanode log?  The logs I have above are from the datanode
(hbase/logs).  I don't see any logs from hadoop/logs directory.
