[jira] [Created] (SPARK-11433) [SQL] Rule EliminateSubQueries does not clean the parent Project's qualifiers

Xiao Li created SPARK-11433:
-------------------------------

             Summary: [SQL] Rule EliminateSubQueries does not clean the parent Project's qualifiers
                 Key: SPARK-11433
                 URL: https://issues.apache.org/jira/browse/SPARK-11433
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 1.5.1
            Reporter: Xiao Li


In the rule EliminateSubQueries, the current implementation just removes the node subquery. 

However, the qualifiers of its parent Project node could still record the subquery's alias name, although the subquery has been removed.
