Hi, @qbadx qbadx
It seems few datanodes are not able to communicate with namenode/keberos server for getting ticket. I will suggest to check below things - 1. Can you pls check if the hostnames of all machines are correct in /etc/hosts 2. check the principals and corresponding hostname in kerberos for the datanodes and namenodes. 3. Paste the logs [job logs] for more details
