Sergey Shelukhin commented on HIVE-11684:
-----------------------------------------
Makes sense. I think (2) might be a better approach, for example join
reordering can be disabled for 1-2 joins.
Actually, I wonder if some CBO features should be disable-able via configs,
like existing Hive optimizations. Should I file a JIRA for that?
Also what is the shipping timeframe for this JIRA? Is the work done on master,
or on a feature branch?
