]

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.
