-------------------------------
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.
