✥ 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
