四种方法:
1.) Shut the HBase cluster - go to ZKcli and rmr /hbase - Start HBase
2.) Move the table, use hbck -fixMeta -fixAssignments, restart the HBase
(not a great option if there is data on the table)
3.) Force an assign on the region for the table and see if it clears it
up
(Should create a new znode)
4.) Go to ZK Cli and check /hbase for unassigned regions and other data
correlating with that region and remove it, then restart HBase
disable 'table_name'
drop 'tab-name'
