Sergey Shelukhin updated HIVE-6418:
-----------------------------------
Attachment: HIVE-6418.01.patch
Added correct handling on 0-length rows (main issue), got rid of some array
allocations when deserializing, other minor changes and fixes. I have run
minitez tests and they passed except for mapjoin_mapjoin; with this patch, that
passes, I am rerunning all tests now.
> MapJoinRowContainer has large memory overhead in typical cases
