Edward Capriolo commented on HIVE-1431:
---------------------------------------
We have a few tickets open, we really need to move all this stuff to a real
parser so we can properly deal with things like ';' or comments like this or
whatever. It is painfully hard to work around all these type of things and we
never get to the root of the problem.
> Hive CLI can't handle query files that begin with comments
