Subject [jira] Updated: (HIVE-935) support LATERAL VIEW

Paul Yang updated HIVE-935:
---------------------------

    Attachment: HIVE-935.6.patch

I've implemented the column aliases as previously mentioned, and made fixes for the issues
Namit had pointed out.

One change is that the patch only requires parenthesis for specifying multiple column aliases
for a UDTF in the select expression. Requiring parenthesis in all cases seemed a little too
verbose.
