Paul Rogers commented on DRILL-5855:
------------------------------------
Already fixed in DRILL-5832. With that change, the option manager throws a user
exception for a missing option declaration, a missing default value or (using
the new methods), a request to return the option as the wrong type. The wording
is neutral to alert us developers when we goof; but also to provide a message
that is OK for users if we really goof and let the error slip through into the
final code.
> Provide a useful error message when the SystemOptionManager is queried for a
> non-existent option

> Project: Apache Drill
> Issue Type: Bug
> Affects Versions: 1.11.0
> Reporter: Timothy Farkas
> Assignee: Timothy Farkas
> Priority: Minor
>
> Currently when the SystemOptionManager is queried for an unregistered option.
> It throws a null pointer exception. I should probably throw and
> IllegalArgumentException with an informative message like "There is no
> OptionDefinition for <option name>. Either you misspelled the option name or
> you need to add an OptionDefinition for this option to the code base."
