master.BackupLogCleaner: Failed to get hbase:backup table, therefore will keep all files org.apache.hadoop.hbase.TableNotFoundException: hbase:backup
I was not able to fix the problem by going into the the hbase zkcli and deleting the data under /hbase-unsecure,after that I start hbase again but not working
Can you try restarting your master. Post master restart hbase:backup table should automatically get created, if it doesn't then check hbase master logs for errors .
Before start working on HBase you can check the status of both Hbase Master and regionserver by using following commands.
sudo service hbase-master status
sudo service regionserver status
If both are not working then start these service first and start working
sudo service hbase-master start
sudo service regionserver start
Hope it will work.
