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.
