             Summary: Incorrect results are returned when using null
                 Key: SPARK-11894
                 URL: https://issues.apache.org/jira/browse/SPARK-11894
             Project: Spark
          Issue Type: Sub-task
    Affects Versions: 1.6.0
            Reporter: Xiao Li


    val ds1 = Seq((new java.lang.Integer(0), "1"), (new java.lang.Integer(22), "2")).toDS()
    val ds2 = Seq((null.asInstanceOf[java.lang.Integer], "1"), (new java.lang.Integer(22), "2")).toDS()//toDF("key", "value").as('df2)

    val res1 = ds1.joinWith(ds2, lit(true)).collect()

The expected result should be 
((null,1),(null,1))
((22,2),(null,1))
((null,1),(22,2))
((22,2),(22,2))

The actual result is 
((0,1),(0,1))
((22,2),(0,1))
((0,1),(22,2))
((22,2),(22,2))
