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.
