@irshan When you add balancer as a role in the HDFS cluster, it indeed will show as not started. So its an expected one. Coming to your main query, it could be possible that when you run the balancer, the balancer threshold could be with in the default percentage of 10, so it won't move the blocks. You may have to reduce the balance threshold and try again.

✥ In CDH6 HBase, the property was removed per https://issues.apache.org/jira/browse/HBASE-15989 because we allow all altering operations without disabling table. cc : @webtube

✥ For the Error "Unrecognized option:-j" kindly manually type the keyword -j instead of copy-paste => Note: you generally notice such exceptions when you have special character pasted ✥ Kindly make sure you first bypass the stuck procedure and locks $ hbase hbck -j /tmp/target/hbase-hbck2-1.3.0-SNAPSHOT.jar bypass -o -r <pid> => For reviewing the stuck procedure kindly navigate to Hmaster ui => Procedure & locks and first bypass the proc id visible in lock section ✥ The you can consider closing the region State before disabling table $ hbase hbck -j /tmp/target/hbase-hbck2-1.3.0-SNAPSHOT.jar setRegionState $i CLOSED $ hbase hbck -j /tmp/target/hbase-hbck2-1.3.0-SNAPSHOT.jar setTableState <tablename> DISABLED => Note: Make sure the 3k regions are all part of the same table " " which you wish to disable/remove ✥ Once table is disabled then you can login into hbase shell and then perform drop table operation $ drop 'tablename'

=> If above steps still gives you issues then you can simply execute step 5 or below Cmd from Standby NN // Bootstrap Standby NameNode. This command copies the contents of the Active NameNode's metadata directories (including the namespace information and most recent checkpoint) to the Standby NameNode. # hdfs namenode -bootstrapStandby Note: Step 1 to step 3 is process of creating new fsimage but if your Active NN is already up and running then I would directly login in to Standby and then perform bootstrapStandby operation
