Wangda Tan updated YARN-6852:
-----------------------------
    Attachment: YARN-6852.004.patch

Again, thanks [~miklos.szegedi@cloudera.com] for your reviews.

bq. could not find a doc about this, so I ask. Is there a reason to have a disable list of
devices, instead of an enable list? 
Actually whitelist doesn't work for me, I tried to debug however I cannot find the root cause.
Since blacklist and whitelist are just two different approaches for the same purpose. I think
we could continue this approach, do you have any concern here? 

And regarding to file name style. I was just about to rename to underscore, however I found
the container-executor itself is "-", I suggest to convert existing files to "-" connected,
otherwise we have to rename a lot of files. I don't quite care about which style to go, I
just want to avoid change too many file.

Attached ver.004 patch, (TODO): unit test related cleanups.
