AuthenticationToken ignored in ResourceManager

Hello!

 

We are running CDH 5.12 and getting the following warnings in both our ResourceManagers. The cluster is configured for HA with two RMs and without KMS.

 

AuthenticationToken ignored: org.apache.hadoop.security.authentication.util.SignerException: Invalid signature

This is logged at least every 15 seconds, which makes it somewhat annoying.

 

Any suggestions on what might be causing it would be great!
