Jason Dere commented on MAPREDUCE-5756:
---------------------------------------

Just tried reverting MAPREDUCE-4470, and yes the test case does pass now.

> Trying to track down HIVE-6401, where we see some "is not a file" errors because getSplits()
is giving us directories.  I believe the culprit is FileInputFormat.listStatus():
> {code}
>                 if (recursive && stat.isDirectory()) {
>                   addInputPathRecursively(result, fs, stat.getPath(),
>                       inputFilter);
>                 } else {
>                   result.add(stat);
>                 }
> {code}
> Which seems to be allowing directories to be added to the results if recursive is false.
 Is this meant to return directories? If not, I think it should look like this:
> {code}
>                 if (stat.isDirectory()) {
>                  if (recursive) {
>                   addInputPathRecursively(result, fs, stat.getPath(),
>                       inputFilter);
>                  }
>                 } else {
>                   result.add(stat);
>                 }
> {code}
