Answer

Hi - Is this warning message impacting your Glue job operation? As a part of  the patch for "Apache Log4j2 Issue (CVE-2021-44228)", the vulnerable JNDI lookup classes were removed from the Log4j jars, which is the reason for the class not found warnings. These warnings can be safely ignored.

Snippet from the [security bulletin](https://aws.amazon.com/security/security-bulletins/AWS-2021-006/):

> We've taken this issue very seriously, and our world-class team of engineers has fully deployed the Amazon-developed Java hot patch available here to all AWS services. The hot patch updates the Java VM to disable the loading of the Java Naming and Directory Interface (JNDI) class, replacing it with a harmless notification message, which mitigates CVE-2021-44228 and CVE-2021-45046.  We will shortly complete our deployment of the updated Log4j library to all of our services

Answer

Hi, 
your question mentions the job failing. Is that so?

In that case you should look in the logs for additional errors, to try to get a better understanding of the logs you can enable [AWS Glue Job Insights](https://docs.aws.amazon.com/glue/latest/dg/monitor-job-insights.html), to try to get some more specific information on the exact error causing the job failure.

If the only issue is the warning error, as mentioned in the previous answer this can be ignored.
