Hello again, On "longer" running jobs (I'm using yarn-client mode), I sometimes get RPC timeouts. Seems like Zeppelin is losing connectivity with the Spark cluster. I can deal with that.
But my notebook has sections stuck in the "Cancel" state, and I can't get them out. When I re-click on cancel, I see "No active SparkContext" in the log. But I can't reload a new instance of the notebook, or kill the one that's stuck, without restarting all of zeppelin. Suggestions? Thanks, Mark
