Hi, Is there a way to provide minThreads and maxThreds for Threadpool through jetty.xml for the jetty that is used by spark Web UI?
I am hitting an issue very similar to the issue described in http://lifelongprogrammer.blogspot.com/2014/10/jetty-insufficient-threads-configured.html I am unable to figure out the location where I can provide jetty.xml , so that it is picked up by spark master daemon.
