[Bug] [Flink、Spark] Tasks such as flink and spark fail to run after kerberos authentication is enabled on Dolphinscheduler #16843
Description
Search before asking
- I had searched in the issues and found no similar issues.
What happened
When kerberos authentication is enabled, the kerberos expiration time is 7 days, and tasks such as flink and spark will fail to be run after 7 days. The kerberos code logic for periodically updating has been added and is valid, allowing the resource center to use it properly. However, the hand running flink and spark tasks still fails and the Dolphinscheduler cluster needs to be restarted
The newly added code is shown below：
After 7 days, the resource center can be used normally, as shown in the following figure
Running the flink live spark task will fail after 7 days, as shown below:
What you expected to happen
The flink and spark tasks can run properly at any time without failing when kerberos expires, and the dolphinscheduler cluster does not need to be restarted
How to reproduce
The expiration time of kerberos is 7 days, after which running tasks will fail
Anything else
no
