> 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.
