@MrNicen This is a very common problem where the table gets stuck in a DISABLING state. First, please try these series of diagnostic and repair steps: First, verify the current state: echo "scan 'hbase:meta'" | hbase shell Try to force the table state change using HBCK2: # Set table to ENABLED state hbase hbck -j ./hbase-hbck2-2.0.2.jar setTableState <table_name> ENABLED # Download HBCK2 if not already present wget https://repository.apache.org/content/repositories/releases/org/apache/hbase/hbase-hbck2/2.0.2/hbase-hbck2-2.0.2.jar If that doesn't work, try cleaning the znode: # Connect to ZooKeeper ./zkCli.sh -server localhost:2181 # Check the table znode ls /hbase/table/<table_name> # Delete the table znode if present rmr /hbase/table/<table_name> If the issue persists, try manually updating the meta table: hbase shell # Disable table disable '<table_name>' # Wait a few seconds, then enable enable '<table_name>' # If that fails, try force disable disable_all '<table_name>' If still stuck, try these repair commands: # Clear the META table state echo "put 'hbase:meta', '<table_name>', 'table:state', '\x08\x00'" | hbase shell # Recreate the regions hbase hbck -j ./hbase-hbck2-2.0.2.jar assigns <table_name> As a last resort, try a full cleanup: # Stop HBase ./bin/stop-hbase.sh # Clear ZooKeeper data ./zkCli.sh -server localhost:2181 rmr /hbase # Remove the META directory rm -rf /hbase/data/hbase/meta # Start HBase ./bin/start-hbase.sh # Recreate the table structure hbase shell create '<table_name>', {NAME => 'cf'} # Adjust column families as needed If none of these steps work, we can try a more aggressive approach: Back up your data: hbase org.apache.hadoop.hbase.snapshot.ExportSnapshot -snapshot <snapshot_name> -copy-to hdfs://backup-cluster/hbase Try a clean META rebuild: # Stop HBase ./bin/stop-hbase.sh # Clear META rm -rf /hbase/data/default/hbase/meta # Start HBase in repair mode env HBASE_OPTS="-XX:+UseParNewGC -XX:+UseConcMarkSweepGC" ./bin/hbase org.apache.hadoop.hbase.util.hbck.OfflineMetaRepair # Start HBase normally ./bin/start-hbase.sh Additional troubleshooting tips: Check HBase logs for specific errors: tail -f /var/log/hbase/hbase-master.log Verify cluster health: hbase hbck -details Monitor region transitions: echo "scan 'hbase:meta', {COLUMNS => 'info:regioninfo'}" | hbase shell If you encounter any specific errors during these steps, please share them and I can provide more targeted solutions.
