Hi
@Sami Ahmad, It isn't the krb5.conf file that is corrupt but more the information that Ambari has in the database to manage your krb5.conf file. From what I am seeing above there isn't a configuration version selected and therefore Ambari is unable to find the configuration data. In my cluster I have a version selected for each which should be the last version. Here is what mine looks like. Notice the latest selected versions.
ambari=> select * from clusterconfigmapping where type_name = 'krb5-conf' or type_name = 'kerberos-env' order by version_tag desc;
cluster_id | type_name | version_tag | create_timestamp | selected | user_name
