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!
