table/partition compaction utility
----------------------------------
Key: HIVE-110
URL: https://issues.apache.org/jira/browse/HIVE-110
Project: Hadoop Hive
Issue Type: Bug
Reporter: Joydeep Sen Sarma
in many cases, we cannot help producing a large number of output files in a
final result table. This can put pressure on the namenode and as well makes
downstream queries potentially inefficient (until we have
combinefileinputformat). Users would like to have a simple utility in hive to
reduce the number of files by concatenating them together. This should apply on
a per partition basis.
Long term - Hive should do this kind of compaction automatically - either
online or offline.
