> According to YARN-9927 analysis. The RMNodeStatusEvent dominates 90% time
> consumption of RM event scheduler.
> Use async-profiler profile the Processing of

> It is definitely worth considering not using these JDK String methods and
> opting for the faster Apache Commons StringUtils.replace() instead.
