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

I am using Storm 1.2.1 and want to profile my workers. 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  does
not mention anything specific.
Am I missing something here?
