Phabricator updated HIVE-4350:
------------------------------

    Attachment: HIVE-4350.D10503.1.patch

mweaverh requested code review of "HIVE-4350 [jira] support AS keyword for table alias".

Reviewers: JIRA

HIVE-4350: Support AS keyword for table alias.  Add simple test.

SQL standard supports AS optional keyword, while creating an table alias.

http://savage.net.au/SQL/sql-92.bnf.html#table reference

Hive gives a error when the optional keyword is used -
select * from tiny as t1;
org.apache.hive.service.cli.HiveSQLException: Error while processing statement: FAILED: ParseException
line 1:19 mismatched input 'as' expecting EOF near 'tiny'

TEST PLAN
  Query test table_alias.q
