[jira] [Created] (SPARK-17008) Normalize query results using sorting

Peter Lee created SPARK-17008:
---------------------------------

             Summary: Normalize query results using sorting
                 Key: SPARK-17008
                 URL: https://issues.apache.org/jira/browse/SPARK-17008
             Project: Spark
          Issue Type: Sub-task
          Components: SQL
            Reporter: Peter Lee


SQL query outputs are not always deterministic, unless there is an explicit order by. This patch injects an explicit sort when the query plan is not supposed to be sorted to make query outputs deterministic. This is inspired by HiveComparisonTest.
