Subject [jira] [Created] (HIVE-6809) Support bulk deleting directories for partition drop with partial spec
Date Wed, 02 Apr 2014 05:35:15 GMT
Navis created HIVE-6809:
---------------------------

             Summary: Support bulk deleting directories for partition drop with partial spec
                 Key: HIVE-6809
                 URL: https://issues.apache.org/jira/browse/HIVE-6809
             Project: Hive
          Issue Type: Improvement
          Components: Query Processor
            Reporter: Navis
            Assignee: Navis


In busy hadoop system, dropping many of partitions takes much more time than expected. In
hive-0.11.0, removing 1700 partitions by single partial spec took 90 minutes, which is reduced
to 3 minutes when deleteData is set false. I couldn't test this in recent hive, which has
HIVE-6256 but if the time-taking part is mostly from removing directories, it seemed not helpful
to reduce whole processing time.
