Subject Flink 1.6.1 Kerberos configuration
Date Fri, 22 Feb 2019 08:28:50 GMT
Hello,

I'm using flink 1.6.1 for streaming. In addition I need access to an
storage layer with kerberos auth. . I added the following parameter in the
flink-conf.yml

security.kerberos.login.use-ticket-cache: true
security.kerberos.login.keytab: /.../*.keytab
security.kerberos.login.principal: *@*

But after a view days (token expired) the job failed with the GSSException:
No valid credentials provided (Mechanism level: Failed to find any Kerberos
tgt)

Do I have to make additional settings or have I missed something else?

Thanks and Best Regards,
Marke
