   I have further investigated the issues I find when running on YARN. What I am trying to do is to add plugins packaged in a jar, using --jars <file> to ship them to the executors. When running on a YARN cluster, the executors are not able to find the plugin class in my custom jar.
   I see that the current executor plugin implementation has additional code to deal with the class loader and its context. I have tried to add that to this PR in a quick hack, and it seemed to work (for YARN).
