Hi Todd, Thanks for the help. I'll try again after building a distribution with the 1.3 sources. However, I wanted to confirm what I mentioned earlier: is it sufficient to copy the distribution only to the client host from where spark-submit is invoked(with spark.yarn.jar set), or is there a need to ensure that the entire distribution is deployed made available pre-deployed on every host in the yarn cluster? I'd assume that the latter shouldn't be necessary.
