Sergey Shelukhin commented on HIVE-12171:
-----------------------------------------
Are you sure? I could see the query fail due to the other bug (cast failure), I
filed another JIRA in your name and have a fix for that.
After that fix, the query doesn't fail, only some tasks. If you are unlucky it
could cause query to fail.
