@revans2 Thank you for the feedback. Following changes should help make
this feature completely optional and pluggable.
- Added `worker.profiler.enabled` to shutdown use of profilers -
- If disabled, UI simply removes the section **Profiling and
Debugging** section.
- If disabled, the supervisor would not add
"worker.profiler.childopts" to worker JVM options - hence avoiding issues with
jvm that does not provide commercial JProfiler.
- Added `worker.profiler.command` to specify which script to use at
supervisor level so that it can be customized for different profiler scheme.
> Dynamic Worker Profiler - jmap, jstack, profiling and restarting worker

> In multi-tenant mode, storm launches long-running JVMs across cluster without
> sudo access to user. Self-serving of Java heap-dumps, jstacks and java
> profiling of these JVMs would improve users' ability to analyze and debug
> issues when monitoring it actively.
