Subject RE: Mapreduce job got stuck
Date Wed, 15 Apr 2015 10:21:51 GMT
Hi Vandana

From the configurations, it looks like none of the NodeManagers are registered with RM because
of configuration “yarn.resourcemanager.resource- tracker.address” issue.  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-”!!!

Hope it helps you to resolve issue

Thanks & Regards
