> Project: Kylin
> Issue Type: Bug
> Components: Job Engine
> Affects Versions: v0.7.2
> Reporter: Yerui Sun
> Assignee: Shaofeng SHI
>
> In GarbageCollectionStep, the hive intermediate table created in step 1 was
> dropped.
> As the table is external table, data was stored in a external hdfs path, like
> '.../kylin-$\{jobId\}/kylin_intermediate_...', which didn't deleted when drop
> hive table.
> Considering the purpose of GarbageCollectionStep, the external data path
> should also be deleted.
