> 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.
