[jira] [Created] (SPARK-19539) CREATE TEMPORARY TABLE need to avoid existing temp view

Xin Wu created SPARK-19539:
------------------------------

             Summary: CREATE TEMPORARY TABLE need to avoid existing temp view
                 Key: SPARK-19539
                 URL: https://issues.apache.org/jira/browse/SPARK-19539
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.1.0
            Reporter: Xin Wu


Current "CREATE TEMPORARY TABLE ... " is deprecated and recommend users to use "CREATE TEMPORARY VIEW ..." And it does not support "IF NOT EXISTS" clause.  However, if there is an existing temporary view defined, it is possible to unintentionally replace this existing view by issuing "CREATE TEMPORARY TABLE ... " with the same table/view name.
