Hi Kishore,
As per the exception given, Node Manager is getting excluded. It might be
happening that you have configured the Node Manager in excluded file using
this configuration in Resource Manager.
Could you check this configuration in RM, is it configured with any file
and that file contains the NM address?
<property>
<description>Path to file with nodes to exclude.</description>
<name>yarn.resourcemanager.nodes.exclude-path</name>
<value></value>
</property>
and also can you cross check this configuration, if you have updated this
then the modification is proper or not.
<property>
<description>Path to file with nodes to include.</description>
<name>yarn.resourcemanager.nodes.include-path</name>
<value></value>
</property>
Thanks&Regards
