Hi Sampath,

Yes, Flink support Kerberos authentication for job submission. You can take
a look at the document here for more detail (https://ci.apache.org/

Also, please make sure to use Flink release 1.4.1 or above, because there
is some regression in previous versions that your job might fail after
deploying to secure YARN.
