                 URL: https://issues.apache.org/jira/browse/HIVE-1499
             Project: Hadoop Hive
          Issue Type: Improvement
          Components: Indexing
    Affects Versions: 0.7.0
            Reporter: John Sichi
            Assignee: He Yongqiang
             Fix For: 0.7.0


This includes providing control over what to do when fine-grained partitions 
are dropped:

* do nothing (but support an ALTER INDEX DROP PARTITION to allow the user to 
clean up manually)
* cascade to drop the entire index partition
* wait for the last fine-grained partition to go away and then auto-drop
