All yarn jobs are failing to get submitted with below error after enabling Ozone.

@Jaguar Welcome to the Cloudera Community!

To help you get the best possible solution, I have tagged our Ozone expert @Devesh  who may be able to assist you further.

Please keep us updated on your post, and we hope you find a satisfactory solution to your query.

Possible Causes & Solutions:
1. Token Expired
The error message shows the token’s maxDate=2025-03-13T06:57:54.532Z, which means it is valid until March 13, 2025. However, if the token was already expired or incorrectly renewed, it would cause this failure.

Solution:
Check token validity using the klist command:

klist -e

If expired, renew the token manually:

hdfs dfs -renewDelegationToken <token>

2. Incorrect or Missing Kerberos Credentials
If the application is running on a Kerberized cluster, YARN must have a valid Kerberos ticket.

Solution:
Ensure the Kerberos ticket is valid:

If the ticket is expired, re-authenticate:

kinit -kt /etc/security/keytabs/yarn.service.keytab yarn/<hostname>@PLATFORMKRB.COM

3. Incorrect Token Renewer Principal
The error message includes:

renewer=yarn

This means the token was issued for YARN to renew, but YARN may not have the required permissions.
Solution:
Ensure the renewer principal is correctly configured in core-site.xml:

<property>
<name>hadoop.security.auth_to_local</name>
<value>RULE:[1:$1@$0](yarn@PLATFORMKRB.COM)s/.*/yarn/</value>
</property>

Restart YARN after making changes.

4. Misconfigured Ozone Token in YARN
If the Ozone token is not being properly renewed, you may need to refresh it.
Solution:
Try manually obtaining a new Ozone token:

hdfs fetchdt -fs o3fs://<bucket>.<volume>/<host>:9862 <token-file>

Pass the token explicitly when running the application.

5. OM (Ozone Manager) Certificate or Service ID Issues
The error mentions omServiceId=<hostname> and omCertSerialId=6. If the OM certificate has expired or the service ID is incorrect, it can prevent token renewal.
Solution:
Check if the OM certificate is valid:

ozone admin cert list

If expired, renew the certificates and restart OM.

6. Mismatched Ozone and YARN Versions
If the Ozone and YARN versions are incompatible, token renewal may fail.

Solution:
Check the Ozone and YARN versions:

ozone version
yarn version

Ensure they are compatible.

Next Steps:
a. Check if the Kerberos ticket is valid (klist).
b. Try renewing the token manually (hdfs dfs -renewDelegationToken).
c. Ensure the correct renewer principal is configured in YARN.
d. Verify Ozone Manager certificates (ozone admin cert list).
e. Restart YARN and OM after making changes.
