So I tried a fix found on the list... changing the mesos version from 0.13.0 to 0.18.0. This apparently worked for someone else on the list in their configuration.
In mine, it still core dumps like this: https://gist.github.com/stevencox/11002498 In this environment: Ubuntu 13.10 Mesos 0.18.0 Spark 0.9.1 JDK 1.7.0_45 Scala 2.10.1 I've tried multiple JDK implementations/versions. All core dump. I've switched back to Mesos 0.13.0 per the Spark on mesos docs. Still core dumps. What am I missing?
