This servlet=C2= =A0should be added to httpserver so that HS2 and LLAP daemons can output fl= amegraphs when their /prof endpoint is hit. Since this will be based on [ht= tps://github.com/jvm-profiling-tools/async-profiler]=C2=A0heap allocation, = lock contentions, HW counters etc. will also be supported in addition to cp= u profiling. In most cases the profiling overhead is pretty low and is safe= to run on production.
