HI Kristoffer, Just removing table data from HDFS will leave hbase in inconsistent state. Yes, you are right you will have to remove table znode from zookeeper to. This is what would i do in your case:
1. remove table data form hdfs (hadoop fs -rmr /hbase/TABLE_NAME) 2. remove znode from zookeeper (hbase zkcli; rmr /hbase/table/TABLE_NAME) 3. start master (it should start now since offending table is removed) 4, run hbase hbck to check state 5. if needed run hbase hbck -repair -repairHoles 6. check zookeeper /hbase/table to see is table is gone if not remove it again and restart master This should fix issue Good luck Samir On Tue, Oct 14, 2014 at 10:11 AM, Kristoffer Sjögren <[email protected]> wrote: > I was thinking of doing that but I suspect that zookeeper keeps metadata of > tables also.
