Yes. I have been using that command to clean up obsoleted hbase tables.

I am hoping to run some utilities for hbase tables backup and then restore to a new cluster, to avoid the lengthy cube build time.

 ${KYLIN_HOME}/bin/kylin.sh org.apache.kylin.tool.StorageCleanupJob --force true --delete true

The above command has worked great for me

I am running kylin 2.5.1.

This command does not work for me:

hbase org.apache.hadoop.util.RunJar /${KYLIN_HOME}/lib/kylin-job-(version).jar org.apache.kylin.job.hadoop.cube.StorageCleanupJob --delete true

I ran:

jar tvf kylin-job-2.5.1-anovadata.jar  |grep StorageCleanup
  1964 Wed Nov 21 09:27:04 EST 2018 org/apache/kylin/storage/hbase/util/StorageCleanupJob$DeleteHTableRunnable.class
16092 Wed Nov 21 09:27:04 EST 2018 org/apache/kylin/sthistory


So there is no class for “org.apache.kylin.job.hadoop.cube.StorageCleanupJob”.

Is this article for kylin after 2.5.1 release?

Thanks.
