Review request for hive and Ashutosh Chauhan.
Bugs: HIVE-7079
https://issues.apache.org/jira/browse/HIVE-7079
Repository: hive-git
Description
-------
Given a query containing common table expressions (CTE) such as:
WITH a AS (SELECT ...), b AS (SELECT ...)
SELECT * FROM a JOIN b on a.col = b.col ...;
Hive CLI executes the query, but logs stack traces at ERROR level during query
parsing:
{noformat}
ERROR metadata.Hive: NoSuchObjectException(message:ccondit.a table not found)

It looks like Hive is attempting to resolve the CTE aliases as physical tables.
