> There are some points to improve the performance of YARN Registry DNS Server.
> - Do not print unnecessary logs (It just needs change log4j.properties)
> - Change some loglevels at points which can affect performance degradation.
> - Use "newFixedThreadPool" instead of "newCachedThreadPool" to prevent OOM
> - Use Blocking on TCP handler. Using non-blocking and sleeping some time("Thread.sleep(500)") is meaningless.
> In our environment, QPS of original yarn dns server is about 5000 (UDP), 100 (TCP).
> Now, QPS of our improved yarn dns server is about 47000 (UDP), 500 (TCP).
> I will make a pull request at https://github.com/apache/hadoop soon.
