Kerberosing the cluster using the AD or Stand alone MIT KDC server

Super Collaborator

Hi Guys,

 

I'm planning to enable kerberos in my hadoop cluster, and need the advise of who already using it.

 

1) which approach is preferable, using the active directory as the lerberos servers or using MIT KDC server?

2) I have alot of impala queries and Spark/ MR jobs, is it hada direct impact on the AD performance if i decide to use it?
