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 dfs to exit safe mode... 2011-03-17 10:50:18,714 INFO org.apache.hadoop.hbase.util.FSUtils: Waiting for dfs to exit safe mode... After the power outage, before we tried bringing things back up, we took several nodes off-line, as their hard drives were failing and needed replacing. Don't know if the loss of those nodes has anything to do with the error msg that we are seeing. Could anybody give us some advice as to where to look for the cause of the HBase failure? We would very much appreciate guidance.
