Create Pre Task hooks for Hive
------------------------------

                 Key: HIVE-1347
                 URL: https://issues.apache.org/jira/browse/HIVE-1347
             Project: Hadoop Hive
          Issue Type: New Feature
          Components: Query Processor
            Reporter: Ashish Thusoo
            Assignee: Ashish Thusoo


Create pre task hooks for hive which can modify configuration parameters or task plans. This
is very useful for implementing a number of different execution policies such as

1. Sending jobs that work on small data sets to a different cluster.
2. Sending jobs that work on archived data sets to a different cluster.

etc.

More details on the actual interfaces will follow soon.
