-----------------------------------
[~csun], to clarify, w/o this patch, there is no problem. If this is case, I
don't think this is a blocker (for 0.15). On the contrary, I'm a little
concerned to include this in 0.15. Please share your thought.

> Sometimes, in SparkMapJoinResolver, after a new SparkTask is generated and
> added to context, it may be processed by the {{dispatch}} method in this
> class. This could introduce wrong plan since {{generateLocalWork}} will
> overwrite existing local work in the SparkTask.
