> This is a long-term plan, and may require major changes.
> From the query, we can figure out the sorting/bucketing properties, and
> change the metadata of the destination at that time.
> However, this means that different partitions may have different metadata.
> Currently, the query plan is same for all the
> partitions of the table - we can do the following:
> 1. In the first cut, have a simple approach where you take the union all
> metadata, and create the most defensive plan.
> 2. Enhance mapredWork() to include partition specific operator trees.
