Issue Type: Sub-task

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))
