Change subject: IMPALA-5892: Allow reporting status independent of fragment instance

Patch Set 2:


Also rebased all the way.
File be/src/runtime/

Line 221:   DCHECK(requests_fragment_detail || omits_fragment_args);
> how about just:
File be/src/runtime/

Line 873:   // in that case).  Coordinator fragment failed in this case so we log the query_id.
> not your change (and doesn't have to be addressed now) but this comment doe
I think the first sentence makes some sense. If there is already an error in query_status_,
then UpdateStatus() will return that rather than the status passed in. If a fragment hit an
error and called CancelInternal(), that would call ReleaseResources(), which closes the coord_sink_.
That should cause GetNext() to return an error, but not the original error.

The second sentence doesn't match anything that I can see.
