Change subject: PREVIEW: IMPALA-3742: partitions INSERTs into Kudu tables
......................................................................


Patch Set 3:

Thanks, Thomas. I think the overall approach makes sense. I haven't gone 
through and left detailed comments yet, but I think it's reasonable to keep 
going along this path, e.g. supporting other DML statements, commenting, tests, 
etc.

Will this end up adding an exchange node if there wasn't one before (i.e. 
that's what we expect)? I guess that might happen because the partitioning 
exprs get set, though it wasn't obvious in DistributedPlanner. Updating the 
planner tests would help.
