-----------------------------------

             Summary: Disallow empty list of paths for file inputs
                 Key: CRUNCH-428
                 URL: https://issues.apache.org/jira/browse/CRUNCH-428
             Project: Crunch
          Issue Type: Bug
    Affects Versions: 0.8.3, 0.10.0
            Reporter: Gabriel Reid
            Assignee: Gabriel Reid


There is currently no checking on the number of input paths supplied in a list to FileSourceImpl
and its subclasses. This can lead to a confusing error when the empty list is deserialized
from CrunchInputs, as an attempt is made to create a Path from an empty string.

The various paths that construct FileSourceImpl subclasses should defensively protect against
creating a file source with an empty list of paths.
