Rui Li commented on HIVE-16155:
-------------------------------
The failure can't be reproduced locally.
[~xuefuz] would you mind take a look at the patch? It's trivial and does the
following changes:
1. Check the small table size first. So if the small table doesn't fit, we
don't need to clone query plan or creating map join, which can be time
consuming.
2. Don't create conditional task if no map join is created. Before the patch,
if no map join is created, we still get a conditional task containing only the
original common join, which is unnecessary and makes the query plan confusing.
> No need for ConditionalTask if no conditional map join is created
