--------------------------------------
Summary: [umbrella] Review switch statements throughout codebase
to add default cases where there are none
Key: DRILL-3521
URL: https://issues.apache.org/jira/browse/DRILL-3521
Project: Apache Drill
Issue Type: Bug
Components: Execution - Flow
Reporter: Jason Altekruse
Assignee: Jason Altekruse
There are a number of places in the code that are missing default branches on
case statements. One particular instance I noticed is in
OptionValue.createOption, which returns null if passed an unexpected type. This
and a few other places in the code could be made a little nicer to work with if
we just provided the standard behavior of throwing an exception.
One additional note, in a number of places where we do have defaults, but the
exception thrown is an UnsupportedOperationException with no message.
DRILL-2680 discusses this problem, so this might be handled over there, but as
we fill in the switch defaults we should try to avoid introducing the new
problem of exceptions lacking descriptions.
