Re: Using several Kerberos keytabs in standalone cluster

[Aljoscha Krettek]

Hi Olga,

I think right now this is not possible because we piggybag on the YARN shipment 
functionality for shipping the Keytab along with the TaskManagers.

I think changing this would require somewhat bigger changes because loading the 
Keytab happens when the TaskManagers are brought up.

Best,
Aljoscha

Using several Kerberos keytabs in standalone cluster

[Olga Luganska]

Hello,

According to the documentation, the security setup is shared by all the jobs on 
the same cluster, and if users need to use a different keytab,
it is easily achievable in Yarn cluster setup by starting a new cluster with a 
different flink-conf.yaml
Is it possible to setup a standalone cluster in such a way that each user can 
run his respective jobs with his own keytab?

Thank you very much,
Olga
