Hi,

On master machine, NodeManager is not running because of “Caused by: java.net.BindException:
Problem binding to [kirti:8040], got from logs.

The port 8040 is in use!!! Configure available port number.


Thanks & Regards

When i made the changes as specified by Rohith, my job is running but it runs only on slave
nodes(amit & yashbir) not on master node(kirti) and still no nodemanager is running on
master node.

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
