Hi,
I am trying to use the FileSource to collect files from HDFS. The HDFS cluster
is secured and has Kerberos enabled.
My Flink cluster runs on Kubernetes (not using the Flink operator) with 2 Job
Managers in HA and 3 Task Managers. I wanted to understand the correct way to
configure the keytab files for this cluster.
Should I just mount the keytab file in all pods and use the
"security.kerberos.login.keytab" config?
For such a setup, what should be the KDC and how do we login to the KDC using
kinit?
I understand that Hadoop automatically renews the TGT using keytab. But this
should only be possible for the renewable lifetime of the ticket (typically 7
days). Does this require us to remount the keytab file again?
Any insights will be helpful here. Thanks
