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.
