Folks,
We had a power outage here, and we are trying to bring our Hadoop/HBase cluster
back up. Hadoop has been just fine - came up smoothly. HBase has not. Our HBase
master log file is filled with just one msg:
2011-03-17 10:50:08,712 INFO org.apache.hadoop.hbase.util.FSUtils: Waiting for
you should have more info on why dfs is in the safe mode in the logs,
you can always leave safe mode
hadoop dfs -safemode leave
but again, thats a symptom, not a problem.

If you are in safe mode it's because not all datanodes have reported
in. So actually NO your hadoop did NOT come up properly.
Check your nn pages, look for any missing nodes. It won't help you
any more than telling you what is online or not.
Good luck!
