Hi Ted,

Find below the configuration I see in yarn-site.xml

<property>
      <name>yarn.resourcemanager.proxy-user-privileges.enabled</name>
      <value>true</value>
    </property>


Regards,
Raja.

Can you check the following config in yarn-site.xml ?

yarn.resourcemanager.proxy-user-privileges.enabled (true)

Cheers

Hi,

I triggered an flink yarn-session on a running Hadoop cluster… and triggering 
streaming application on that.

But, I see after few days of running without any issues, the flink application 
which is writing data to hdfs failing with below exception.

Caused by: 
org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.token.SecretManager$InvalidToken):

Can someone please help me how I can fix this. Thanks a lot.
