-------------------------------

             Summary: GarbageCollectionStep dropped Hive Intermediate Table but didn't drop external hdfs path
                 Key: KYLIN-978
                 URL: https://issues.apache.org/jira/browse/KYLIN-978
             Project: Kylin
          Issue Type: Bug
          Components: Job Engine
    Affects Versions: v0.7.2
            Reporter: Yerui Sun
            Assignee: ZhouQianhao


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.
