Adam Faris updated HADOOP-6616:

    Attachment: hadoop-6616.patch.2

Hi Joep, 

Thanks for reviewing the patch and providing feedback.  That double negative ... uggh! :)
  I wasn't aware of 'topology.script.number.args' so thanks for mentioning it.  Here's an
updated patch which includes updates to sample scripts for looping over STDIN, topology.script.number.args,
and why hadoop should care about rack awareness.

should be augmented to include a sample script.
