> @maomaodev Generally, the executor is supposed to use the delegation token instead of keytab to access kerberized HDFS. I wonder how do you set up your Kerberos auth for Spark? And what's the behavior before this PR. 1. Yes, the executor does use delegation token, but based on the stacktrace provided above, the code is throwing an exception before adding the delegation token. <img width="1101" alt="企业微信20250107-171644@2x" src="https://github.com/user-attachments/assets/f32dd6ce-c577-495c-bc4f-200c3c156599"; /> 2. We use Kyuubi for submission, using the parameter spark.kubernetes.kerberos.krb5.path. <img width="1455" alt="企业微信20250107-173420@2x" src="https://github.com/user-attachments/assets/e8a4800d-75b7-4803-aaee-496971011166"; /> 3. Prior to this PR, we were using Spark 3.4.2, and the executor did not mount the Hadoop conf during startup. The executor logs showed simple authentication. <img width="1449" alt="企业微信20250107-172445@2x" src="https://github.com/user-attachments/assets/c8fc9aeb-99bc-4f23-bc56-44d8a4160c08"; /> -- This is an automated message from the Apache Git Service.
