Sean Owen resolved SPARK-9621.
------------------------------
Resolution: Duplicate
Pretty sure this is a subset of the general problem of using case classes in
the shell. They don't end up being the same class when used this way. I don't
know if it's a Scala shell thing or not, and I am not aware of a solution other
than "don't use case classes in the shell"
> Closure inside RDD doesn't properly close over environment

> Key: SPARK-9621
> URL: https://issues.apache.org/jira/browse/SPARK-9621
> Project: Spark
> Issue Type: Bug
> Affects Versions: 1.4.1
> Environment: Ubuntu 15.04, spark-1.4.1-bin-hadoop2.6 package
> Reporter: Joe Near
>
> I expect the following:
> case class MyTest(i: Int)
> val tv = MyTest(1)
> val res = sc.parallelize(Array((t: MyTest) => t == tv)).first()(tv)
> to be "true." It is "false," when I type this into spark-shell. It seems the
> closure is changed somehow when it's serialized and deserialized.
