Varun Vasudev commented on YARN-1781:
-------------------------------------
> 1. Disk Size can come down when some tasks finishes and service deletes few
> data from local directory.
> There are more chances that this Disk Full may be temporary scenario because
> of many tasks accessing local directories.
>
> So there can be counter checks to ensure that these directories are added
> back to good list of directories.
> Else these directory may lost.
This will be taken care when I fix YARN-90 which brings back bad disks once
they've recovered.
> 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.
