LGTM - thanks @gilgenbergg for the patch. Overall, this is a great start. During the merge, I fixes the licenses (wrong/missing) and did some minor cleanups. There some issues though. Please, (1) revisit the broadcast handling (don't read broadcasts at the driver), (2) make the checking of masks and approving of union slices separate functions with hash lookups and early-abort instead of full nested loop joins, and (3) ensure that common code paths don't go though (misuse) exception handling. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
