i'm new in learning hadoop and i have some question that i didnt find the answer anywhere. as i learn all put yarn/resourcemanager with namenode and i know its possible to use yarn/RM own(dedicated) server. How to setup hadoop cluster with seperate yarn ?
what parameter that makes namenode know location yarn?
@tigerpig 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 .
