I have enabled kerberos in my cluster. I am unable to access my HDFS or all UI, its required authentication. I have tried spnego for this. Still my issue is persist. Could any please provide me the steps for this issue. How to access my UI even my cluster is in kerberosized?
There is post install steps that you should perform. Configuring HTTP Authentication for HDFS, YARN, MapReduce2, HBase, Oozie, Falcon and Storm
You should be able to access the UI's after this
I have tried this link after enabled Kerberos cluster. Still it's not working.
I have tried to install MIT in my windows machine, but when I am clicking on get tickets it's prompting for principal and password. I am not sure on this well.
If I enabled my cluster as kerberos and trying to access the HDFS webpage and prompting for authentication. What could be the username and password?
Hi Mohamed, have you tried using your LDAP/ active directory login as username and password (this s how your kerberos is setup?).
Actually I have not configured any LDAP/AD in my cluster. If you dont mind can u share the links or docs for LDAP setup.
If you tried any docs for this issue. Can you please provide me.
Can you give me a screenshot your MIT UI on windows? Have you tried the root/admin@REALM plus its password?
For the AD integration, you will need to get the credentials and specific config et LDAP(S) URL which is site-specific from you AD Admin these are the major steps
Set the correct parameters
# ambari-server setup-ldap
Restart so Ambari picks up the new changes
# ambari-server restart
Restart the agents
# ambari-agent restart
The below will synchronize all the valid users in your LDAP with your cluster which might not be what you want !!!
# ambari-server sync-ldap --all
You can synchronize a particular group and users, and also to understand the tasks to undertake please read the latest HDP 2.6 doc
Hope that helps
