Josh Wills commented on CRUNCH-569:
-----------------------------------

[~mkwhitacre] yeah, that was what I had in mind, though I didn't think through the amount
of copy-and-paste-ish code that would be required (sorry about that.) Happy to move ahead
w/this approach though.

> A cached PCollection/PTable built by Avros using SparkPipeline seem to reuse avro objects.
Here is a test that shows this behavior
> https://gist.github.com/nasokan/531b4ff9bf827d0835ab
> I would expect the output of this program to create a pair with same key, value. However,
this produces Pair with different key value. I have tested this with text file input source
and it works as expected. Removing cache() produces expected result.
