             Summary: Discard the Jobs while Droping/Purging the Cube
                 Key: KYLIN-1863
                 URL: https://issues.apache.org/jira/browse/KYLIN-1863
             Project: Kylin
          Issue Type: Bug
            Reporter: Richard Calaba
             Fix For: all, v1.5.2.1, v1.5.2


I have observed that following scenario on UI leaves uncleaned meta-data in Kylin:

1) I have a error status job in Monitor for my Cube. I drop the cube from UI. I still see the error status jobs in Monitor after Dropping the Cube. If I try to Discard the job -> I am getting NPE. Didn't test the same if Purge used instead of Drop - but this needs to be checked as well.

2) Not 100% sure - but I have a feeling that if I Drop cube from UI before Purging it 1st - some job execution metadata (finished build jobs) stay in the system ... (intermediate tables/HDFS folders/...). It is hard to find a prove now when my system is polluted with old job executions. This could be checked while working on 1) above.
