you can set any java options to enable java profilers via the topology.worker.childopts when submitting the topology.

I've set worker.profiler.enabled to true in the config and the UI's showing the values below so everything should be fine. I've modified the childopts so that it works with Oracle Java 9 and flight.bash works when I run it manually. | worker.profiler.childopts | "-XX:+UnlockCommercialFeatures -XX:+FlightRecorder" | | worker.profiler.command | "flight.bash" | | worker.profiler.enabled | true | I have 'Jstack', 'Restart worker' and 'Heap' available as actions and clickable when I select a worker but there is nothing about profiling. The documentation on http://storm.apache.org/releases/1.2.1/dynamic-worker-profiling.html does not mention anything specific. Am I missing something here?
