Hi,
I’m planning an MIT KDC installation for a hadoop cluster consisting of X
clients with Y kerberized services each. The KDCs are rather powerful machines
with 64 cores and 125G of RAM. I want to get the most out of this hardware and
use the mininum number of KDCs required. Is there a rule of

Since I don’t know too much about the KDC architecture, sorry for the
dilettante questions.

Still very valuable since I haven’t been able to find answers to any of these
questions elsewhere.

Thank you so much for confirming that the KDCs are fast. This saved me a ton of
time writing my own tests, etc. Andrew, as far as workers, is it one worker per
core in general as Russ theorized?
Otherwise, I think I’m all set for now.
Thanks!!
