I'm not a JNI expert. But it would have to be that whatever is calling
registered/launch is running from a thread not launched within the doAs. Or it
didn't propogate the environment properly through the JNI or pushed a subject
on top of ours. I think you need a mesos expert to look at this.
You could wrap where it is launching tasks but this can cause other issues.
see SPARK-1676 and https://github.com/apache/spark/pull/621
@mateiz @pwendell Are there any Mesos experts around that knows more about
how exactly spark interacts with mesos?
