Josh Wills updated CRUNCH-557:
------------------------------
Attachment: CRUNCH-557.patch
Fix for this, which is tiny and probably a bit too hacky at the moment.
[~gabriel.reid] or [~mkwhitacre], could you clean this up and merge it to
master when you're happy with it? I'll be offline the next few days.

> From the user list:
> I was trying to determine effect of changing JoinStrategy on a Spark
> pipeline. I noticed that my pipeline works fine with DefaultJoinStrategy,
> however I could not get it to working with MapSideJoinStrategy and
> BloomFilterJoinStrategy. For MapSideJoinStrategy I get an exceptions[1] on
> driver itself and for BloomFilterJoinStrategy I get exceptions[2] in one of
> the stages. I have not tried to do any configuration changes but I did run
> tests with datasets of different sizes to ensure that my PCollection is small
> enough to fit in memory. I am running spark in yarn-client mode with Crunch
> 0.11.0-cdh5.4.2.

> [2] https://gist.github.com/anonymous/b02a82401a30a69f1cff
> The bug is in the SparkRuntime.distributeFiles method, which needs to include
> a scheme for the URI it's handing to Spark.
