Actually you have several config file for RM under /etc/hadoop/conf dir
this is mainly host all the core services configs , so you just only should make sure that you are using a proper config inside yarn-site.xml .

inside that file you can specify the location of you RM .

if possible attache you yarn-site.xml conf file here to validate .

 

also it's a good idea to check the logs for RM once you start it to see the reason of this start up failure .
