    @yufeldman , sorry for the delay in reviewing.  I will review the parallelizer related
enhancements (the new code since existing parallelizer is not impacted) and related planner
changes.  I probably won't review the protobuf changes since I am not completely familiar
with that code.

> Today Drill Query execution is optimistic and stateful (at least due to data exchanges)
- if any of the stages of query execution fails whole query fails. If query is just simple
scan, filter push down and project where no data exchange happens between DrillBits there
is no need to fail whole query when one DrillBit fails, as minor fragments running on that
DrillBit can be rerun on the other DrillBit. There are probably multiple ways to achieve this.
This JIRA is to open discussion on: 
> 1. agreement that we need to support above use case 
> 2. means of achieving it.
