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.
