Change subject: IMPALA-2758: Remove BufferedTupleStream::GetRows

Patch Set 4: Code-Review+2


Looks good, just did a final pass and caught a couple more things. If you fix those and rebase
then I can start the merge.
File be/src/exec/partitioned-hash-join-node.h:
PS4, Line 482:   bool output_null_aware_probe_rows_running_;
Longer-term we should think about ways to reduce the sheer number of stateful member variables
in this class and make the state machine in GetNext() easier to understand.
File be/src/exec/
PS4, Line 949:     RowBatch null_build_batch(child(1)->row_desc(), state->batch_size(),
This can fit on one line.
PS4, Line 962:       null_build_batch.Reset();
We should add a RETURN_IF_CANCELLED() check here, similar to the one below (I think this was
an oversight in an earlier patch).
PS4, Line 1074:       RowBatch build_batch(child(1)->row_desc(), state->batch_size(),
This can fit on one line.
