Sorry, premature send…

If you are daring and have a backup of your Ambari database, you can remove the relevant entries
from the kerberos_principal_host table and then click then regenerate the missing keytabs.

Matthew…

You can try to Regenerate Keytabs and click the check box on the first popup page that indicates
to only create the missing keytab files. However the Ambari server may not know that the keytabs
are missing from that one host.

If you are daring and have a backup of your Ambari database, you can remove the relevant entries
from the kerberos_principal_host table.

Subject: Method to re-populate keytabs on a single host?

Hello Ambari Users,

I was wondering if anyone has come across a way to push the Keytabs for a specific host/component
when using automated Kerberos in Ambari?  If the Keytabs get deleted off of a host ,currently
the only solution I can see (via Ambari) is to regenerate all the Keytabs for the cluster
which requires a restart of all services.

Thanks,
Matthew Bruce
