Hi Joel, StorageCleanupJob can be run at anytime. It will delete the htables/hdfs folders that have no reference, so it is safe. The "offline" means by manual (not by kylin)
MetadataCleanup, would be better to run when there is no running job; and take a backup before clean is always recommended. 2016-10-17 22:29 GMT+08:00 Joel Victor <[email protected]>: > In order to cleanup kylin metadata, HBase tables and HDFS.
