[jira] [Created] (SPARK-11214) Join with Unicode-String results wrong empty

Hans Fischer created SPARK-11214:
------------------------------------

             Summary: Join with Unicode-String results wrong empty
                 Key: SPARK-11214
                 URL: https://issues.apache.org/jira/browse/SPARK-11214
             Project: Spark
          Issue Type: Bug
          Components: PySpark, SQL
    Affects Versions: 1.5.0
            Reporter: Hans Fischer
            Priority: Critical


I created a join that should clearly result in a single row but return: empty. Could someone validate this bug?

hiveContext.sql('SELECT * FROM (SELECT "c" AS a) AS a JOIN (SELECT "c" AS b) AS b ON a.a = b.b').take(10)

result: []

kind regards
Hans
