Mike Drob commented on ACCUMULO-4488:
-------------------------------------

bq. +Note that on an existing cluster the server side changes will a full 
cluster shutdown and restart. You should
Missing a word.

bq. +- version: 1.7.2
I was going to ask if this should be 1.8.0, but spot checking our docs we are 
not consistent on this at all.

bq. +*A*: This indicates that the Monitor has not been able to successfully log 
in a client-side user to read from the +trace+ table. Accumulo allows the 
TraceServer to rely on the property +general.kerberos.keytab+ as a fallback 
when logging in the trace user if the +trace.token.property.keytab+ property 
isn't defined. Some earlier versions of Accumulo did not do this same fallback 
for the Monitor's use of the trace user. The end result is that if you just 
configure +general.kerberos.keytab+ you will end up with a system that properly 
logs trace information but can't view it.
nit: remove "just"

> clean up several gaps in the docs that I stumbled on while setting up a 
> cluster with kerberos for clients:
> * document setting up a superuser on an existing system that's enabling 
> kerberos
> * include example of verifying access for the superuser
> * per-user client configuration gives wrong filename
> * per-user client configuration required additions for kerberos missing 
> {{rpc.sasl.qop}}
> * document {{trace.token.property.keytab}}
> * note required permissions for trace user (Table.READ, Table.WRITE, 
> Table.ALTER_TABLE)
