Steve Loughran commented on HADOOP-9310:
----------------------------------------
The current behaviour from the base class is (unintetionally?) to return an
empty location array on a directory.
This is a consequence of a directory having length 0, so the "gone off the end
of the file" logic kicks in
{code}
if (status.getLen() <= start) {
return new BlockLocation[0];
}
{code}
> {FileSystem,FileContext}.getFileBlockLocations() are incompletely and
> incorrectly specified

> The javadocs of the {{getFileBlockLocations()}} methods in {{FileSystem}} and
> {{FileContext}} incorrectly specify the result when a nonexistent region is
> passed in (it's an empty array, not null), and nowhere is the response to a
> call of the method against a directory defined.
