Actually, I have Hadoop Hortonworks Cluster with Kerberos enabled.
Users to access are in AD repository.
I can add some users and test that users could submit their jobs successfully.
But the issue here that I have to add every user on all nodes and also register every user keytab on all nodes.
This is ok for 1 or 2 users but not for 50 or 100 😞
I am creating keytab using kutil , so i have to ask every user to tape his password!!
Is there any other tip to do this?
How can I register keytabs for a domain not per user?
Should I do it per user?
Any idea will be appreciated.
