HBASE-13755 the superuser we add by default (the process running hbase) does not take in consideration the keytab credential.
We have an env with the process user being hbase and the keytab being hbasefoo.
from Superusers TRACE I see, the hbase being picked up
from the RS audit I see the hbasefoo making requests
looking at the code in HRegionServer we do
HBASE-13755 we were initializing the super user in the ACL coprocessor, so after the login. but now we do that before the login.
I'm not sure if we can just move the Superuser.initialize() after the login Mikhail Antonov?
