> From Matteo (https://reviews.apache.org/r/9416/diff/2/?file=258262#file258262line402):
> looking at the source, it seems that checking the return value and throw an exception seems a good way to shoot ourselves in the foot. I've added that check in other places and not I'm regretting that...
> because a return false doesn't really mean I'm not able to delete the file/dir.
> maybe the file is already deleted by someone else, or renamed...
> You want to throw an exception only if the file/dir is still there...
> so if we don't trust that the API will provide an exception is case of failure
> we should do something like
> {code}
> if (!fs.delete(workingDir, true)) {
>   // Make sure that the dir is still there
>   if (fs.exists(workingDir)) { 
>     throw new IOException("Unable to delete " + workingDir);
>   }
> }
> {code}
> We can add the following method to FSUtils:
> void delete(Path f, boolean recursive) throws IOException;
