Anuj updated YARN-9241:
-----------------------
Description:
RmController contains a hardcoded if and else block for type of scheduler and
decides which page to use for which scheduler.
[https://github.com/apache/hadoop/blob/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-server/hadoop-yarn-server-resourcemanager/src/main/java/org/apache/hadoop/yarn/server/resourcemanager/webapp/RmController.java|http://example.com]
This if else block makes it hard to introduce a new scheduler and corresponding
webpage with modifying the existing RMController class.
It would be great if we make it extendable.
