>                 URL: https://issues.apache.org/jira/browse/DRILL-2623
>             Project: Apache Drill
>          Issue Type: New Feature

>            Assignee: Jacques Nadeau
> This is an enhancement request to expose only well tested and useful parameters to the
end user.
> For example, we don't want to allow all users to change internal configuration parameters,
like exec.min_hash_table_size or enable features that are not ready for prime time ( store.parquet.enable_dictionary_encoding
for example). 
> However, sometimes in order to achieve optimal performace some configuration fiddling
will be absolutely necessary. We can allow different users with different privileges have
an ability to change settings.
> One of the proposals to achieve this is to create a view on top of sys.options that will
be created on drills start up and have privileged access 
> a) to the information in the view - show only things that particular user is allowed
to see 
> b) have privileged access to "ALTER SYSTEM/SESSION" commands.
