John Vines commented on ACCUMULO-263:
-------------------------------------
Wow... I butchered this description while typing it.
Fail fast check for security issues, i.e. read and write permissions. However,
this will then require to the client to be fully aware of the security
mechanism used, which may not mesh nicely with the changes to the authenticator
in trunk. I'm thinking we may want to table this as an unneeded feature.

> Currently connection.createScanner/createBatchWriter only throws
> TableotFoundException, it does no checking for quick failures. There is an
> efficiency hit in doing a server hit. We may want to consider keeping a
> zoocache on the client end for checking. It's not the most secure, but the
> permissions are checked server side so any attempt to subvert the security in
> the initial check will not change the final result.
