-----------------------------------
Kylin does not guarantee garbage cleaning for discarding jobs now. Instead
admins are supposed to periodically use StorageCleanupJob to clean
> 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 not cleaned properly.
> It could be that I didn't execute Purge before 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
> having a 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.
