Hyukjin Kwon resolved SPARK-17145.

    Resolution: Cannot Reproduce

The test at least looks passing in the master. I am resolving this as a {{Cannot Reproduce}}.

>             Project: Spark
>          Issue Type: Bug
>    Affects Versions: 2.0.0

> The unit test here (https://gist.github.com/abdulla16/433faf7df59fce11a5fff284bac0d945) describes the problem. 
> It looks like Spark is having problems serializing a Scala Seq when it's part of an object with many fields (I'm not 100% sure it's a serialization problem). The deserialized Seq ends up with as many items as the original Seq, however, all the items are copies of the last item in the original Seq.
> The object that I used in my unit test (as an example) is a Tuple5. However, I've seen this behavior in other types of objects. 
> Reducing MyClass5 to only two fields (field34 and field35) causes the unit test to pass.
