[jira] [Created] (KYLIN-1847) Cleanup of Intermediate tables not working well

Richard Calaba created KYLIN-1847:
-------------------------------------

             Summary: Cleanup of Intermediate tables not working well
                 Key: KYLIN-1847
                 URL: https://issues.apache.org/jira/browse/KYLIN-1847
             Project: Kylin
          Issue Type: Bug
    Affects Versions: v1.5.2, v1.5.2.1
            Reporter: Richard Calaba


I have realized that Hive tables kylin_intermediate_<cubename>_<snapshotdates> after cancelling all pending build jobs and dropping the cube are no cleaned properly. 

It could be that I didn't execute Purge befor Dropping the cube ... just a theory, not 100% sure.

I also suspect that on hdfs in the /kylin/kylin_metadata/ directory I have too many uncleaned data ... considering that I have just now only 1 cube wih pending build job I see too many subdirectories there ...

There might be some relation to he JIRA I already reported as well ... https://issues.apache.org/jira/browse/KYLIN-1828 - but again not 100% sure this is the sole reason.

My impression is that the cleanup logic after the Drop cube needs to be re-checked.
