Description

NamenodeHeartbeatService has been found to log the errors when querying protected Namenode JMX APIs. We have been able to work around this by running kinit with the DFS_ROUTER_KEYTAB_FILE_KEY and DFS_ROUTER_KERBEROS_PRINCIPAL_KEY on the router.

While investigating a solution, we found that doing the request as part of a  UserGroupInformation.getLoginUser.doAs() call doesn't require to kinit before.

The error logged is:
