This generally happens when the kerberos ticket that is being used to authenticate with the Hadoop cluster has expired. If the kerberos credentials are configured in Druid using `druid.hadoop.security.kerberos.principal` and `druid.hadoop.security.kerberos.keytab`, Druid takes care of refreshing the ticket before expiry. If not, you might be relying on an external service to renew the ticket cache and it might be worth checking that out to see if the renewal is working as expected. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
