Subject [jira] Created: (HIVE-995) early stop of the mapper/reducer
Date Wed, 16 Dec 2009 17:28:18 GMT
early stop of the mapper/reducer
--------------------------------

                 Key: HIVE-995
                 URL: https://issues.apache.org/jira/browse/HIVE-995
             Project: Hadoop Hive
          Issue Type: New Feature
          Components: Query Processor
            Reporter: Namit Jain
             Fix For: 0.5.0


1. A mechanism should be provided where the user can specify that there is a error in his
custom script. The whole job/query should be 
stopped at that time. 

2. It would be useful if the offending row on which the script failed can be provided easily.

3. It would be very useful if on a rerun, only that mapper/reducer runs so that it is easy
to debug the problem.

The above 3 can be split into different jiras also.
