Is it a failed split? Its not an offlined parent with split daughters? It doesn't seem so. I'd grep logs to see if I could figure history of the regions but seems like you did that already. You could merge the regions without data loss. You need to first take the table offline and then run the merge tool.
hbase> disable "TABLENAME" Then once its offline: ./bin/hbase org.apache.hadoop.hbase.util.Merge That should printout usage.
