> ExecutorThreadCPUTime and ExecutorThreadUserTime relies on thread mx bean cpu
> metrics when available. At some point, the thread name which the metrics
> publisher looks for has changed causing no metrics to be published for these
> counters.
> The above counters looks for thread with name starting with
> "ContainerExecutor" but the llap task executor thread got changed to
> "Task-Executor"
