Ravi Prakash commented on YARN-90:
----------------------------------

Hi Song! Thanks a lot for your offer to contribute. It would be great if you could please
also share your patch. Could you please also clarify what "tt" you are referring to in "tt
also adds a new metric of the number"?
I will go ahead and test the pre-existing patch anyway.

> MAPREDUCE-3121 makes NodeManager identify disk failures. But once a disk goes down, it
is marked as failed forever. To reuse that disk (after it becomes good), NodeManager needs
restart. This JIRA is to improve NodeManager to reuse good disks(which could be bad some time
back).
