Varun Vasudev commented on YARN-1781:
-------------------------------------
The attached patch adds support for checking disk utilization as part of the
checkDirs function in DirectoryCollection. Disk utilization can be specified as
a percentage via the yarn config, with the default value set to 1.0F(use the
full disk).
> NM should allow users to specify max disk utilization for local disks

> This is related to YARN-257(it's probably a sub task?). Currently, the NM
> does not detect full disks and allows full disks to be used by containers
> leading to repeated failures. YARN-257 deals with graceful handling of full
> disks. This ticket is only about detection of full disks by the disk health
> checkers.
> The NM should allow users to set a maximum disk utilization for local disks
> and mark disks as bad once they exceed that utilization. At the very least,
> the NM should at least detect full disks.
