Hi Thanks for your articles.They give a great insight on Hadoop.

Currently we have kerberos enabled in our cluster using IPA free.We want to migrate it to Microsoft AD kerberos.

So,we are planning to disable kerberos and then enable it using the microsoft AD.I would like to know if there would be any impact on the existing services because of this.Also do you have any detailed documentation for migrating from MIT kerberos to AD kerberos ?

Thanks,

    If you disabled kerberos via ambari and removed SPNEGO from all services where you have configured then it should not be any problem by setting it up with MS AD.
    But if you face any problem then feel free to let me know, I will be always here to help you.
