Does any one know why i am seeing these warnings in my Resource manager logs ?
These are coming every minute and thats why they are concerning, there were no changes made lately to the cluster. Could somoene throw some light on these errors and point me to the right direction for further investigation.
IMPORTANT AuthenticationToken ignored: Invalid AuthenticationToken type

YARN (MR2 Included)
What service, roles, or host is the last message coming from? The only service that I know of that runs under the mapred account is the JobHistory server. This could mean there is an issue with jobs transitioning between the RM and JH when they are aged out.
The first on is not very helpful, but it could indicate that some user/service is trying to interact with the RM but has a bad token so it fails.
