May be you can confirm any NM’s are registered with RM. In the below, there is space after “resource-“ but “resource-tracker” is single without any space. Check after removing space. <name>yarn.resourcemanager.resource- tracker.address</name> Similarly I see same issue in “yarn.nodemanager.aux- services.mapreduce.shuffle.class” where space after “aux-”!!!
