Bibin A Chundatt commented on YARN-8434:
----------------------------------------
Thank you [~subru] for looking in to the issue
I have configured the following in NM as per the documentation
[http://hadoop.apache.org/docs/r3.0.1/hadoop-yarn/hadoop-yarn-site/Federation.html]
{code:java}
yarn.client.failover-proxy-provider
org.apache.hadoop.yarn.server.federation.failover.FederationRMFailoverProxyProvider
{code}
But the same is used for NM-RM communication too. {{ServerRMProxy}} also uses
{{yarn.client.failover-proxy-provider}} for failover .
Seems NM also will try to connect to RM using
{{FederationRMFailoverProxyProvider}}
{code:java}
<property>
<description>When HA is enabled, the class to be used by Clients, AMs and
NMs to failover to the Active RM. It should extend
org.apache.hadoop.yarn.client.RMFailoverProxyProvider</description>
<name>yarn.client.failover-proxy-provider</name>
<value>org.apache.hadoop.yarn.client.ConfiguredRMFailoverProxyProvider</value>
</property>
{code}
> Nodemanager not registering to active RM in federation
