Virgil Palanciuc commented on SPARK-17594:
------------------------------------------
FWIW, they may not be related; my program works if I replace "===" with "<=>";
whereas this example doesn't work with "<=>", either. It's still a bug :)
> Bug in left-outer join
> ----------------------
>
> Key: SPARK-17594
> URL: https://issues.apache.org/jira/browse/SPARK-17594
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.0
> Reporter: Virgil Palanciuc
>
> I have a bug where I think a left-join returns wrong results, by mistakenly
> matching long values that are identical on 32bits (differ in their upper
> halves).
> Trying to reproduce it in the console - I get
> "ArrayIndexOutOfBoundsException" - not identical, but it may be related:
> {code}
> scala> val b = Seq(1L, 3L).toDF("x")
> b: org.apache.spark.sql.DataFrame = [x: bigint]
> scala> val a = Seq(17179869185L, 17179869186L).toDF("x")
> a: org.apache.spark.sql.DataFrame = [x: bigint]
> scala> b.join(a,Seq("x"), "left_outer").show()
