Description

Currently, I cannot see an HTTP web server in DAGAppMaster, but sooner or later we'll need one. I'm attaching some tickets which are related.
As a reference, we can start with a simplified version of Hive's HTTPServer which runs in HiveServer2: [-https://github.com/apache/hive/blob/master/common/src/java/org/apache/hive/http/HttpServer.java-]

 

I found WebUIService which can be reused to add some useful endpoints: jmx, conf, stacks
