[jira] [Created] (HIVE-7590) Should not fire a merge job if hive.hadoop.supports.splittable.combineinputformat is set to false

Chengbing Liu created HIVE-7590:
-----------------------------------

             Summary: Should not fire a merge job if hive.hadoop.supports.splittable.combineinputformat is set to false
                 Key: HIVE-7590
                 URL: https://issues.apache.org/jira/browse/HIVE-7590
             Project: Hive
          Issue Type: Bug
          Components: Query Processor
    Affects Versions: 0.10.0
            Reporter: Chengbing Liu


When hive.hadoop.supports.splittable.combineinputformat is set to false, a map can process only one file, making the merge job not actually doing merging. The merge job should only be fired if hive.hadoop.supports.splittable.combineinputformat is set to true.

I have observed this with 0.10. It seems trunk also has this problem.
