I just become into the need to bring Flink into a yarn system, that is configured with kerberos. According to the documentation, I changed the flink.conf.yaml like that:
security.kerberos.login.use-ticket-cache: true security.kerberos.login.contexts: Client
I know that providing a keytab is the prefered,
but I have to do a special request to receive one. ;-)

Could you tell us the version / build commit of Flink that you’re using?

Can you check the logs of the JobManager? (maybe in DEBUG level), to see if you see something that tries to establish a connection with it?
Are you sure you are properly authenticated to access the JM?

Had another quick look at the error trace you provided, the problem doesn’t seem to be related to Kerberos authentication.
For some reason the JobManager simply isn’t reachable from the client, as Robert has pointed out. There should be some clue about this in the JM logs.
