Aaron T. Myers updated HDFS-3026:
---------------------------------

    Attachment: HDFS-3026.patch

Thanks a lot for the review, Eli. Here's an updated patch.

Good idea re: trash emptier thread. I've done that in this patch.

As for the other exits in NameNode - all of those are as exit codes from shell commands (e.g.
format, bootstrapStandby, etc.), or from the the static main function, none of which I think
really benefit from calling this method. Good point about making the error message more generic,
though. I've gone ahead and done that.
