Subject [jira] Created: (HIVE-629) concat files needed for map-reduce jobs also
Date Mon, 13 Jul 2009 18:03:14 GMT
concat files needed for map-reduce jobs also
--------------------------------------------

                 Key: HIVE-629
                 URL: https://issues.apache.org/jira/browse/HIVE-629
             Project: Hadoop Hive
          Issue Type: Improvement
          Components: Query Processor
    Affects Versions: 0.4.0
            Reporter: Namit Jain
            Assignee: Namit Jain


Currently, hive concatenates files only if the job under consideration is a map-only job.


I got some requests from some users, where they want this behavior for map-reduce jobs also
- it may not be a good idea to turn it on by default.
But, we should provide an option to the user where the concatenation can happen even for map-reduce
jobs.
