Hi Benjamin,
Thank you for your reply.
Option 1 - did not work, as expected 🙂 Option 2 - In the link, at step b2, there's this command: UserGroupInformation.loginUserFromKeytab("example_user@IBM.COM", "/path/to/example_user.keytab");
Does this mean that my user (later on it will be a system user) needs to have a keytab created on the linux file system and distributed to all the nodes?
Moreover, it might not be a great option, but isn't this authentication possible using only username/password ? Option 3 - I'm using the current mechanism as it is the only one I found some examples on the net. I checked shortly on PAM/LDAP, I'm not sure yet if that will require some changes from the Hadoop cluster side. If not, I'll be happy to try it
