Richard Calaba updated KYLIN-1863:
----------------------------------
Description:
I have observed that following scenario on UI leaves uncleaned meta-data in
Kylin:
1) I have an 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.
