Varun Vasudev commented on YARN-5274:
-------------------------------------
# Making it a sub-task makes sense; converted.
# I wouldn't combine this YARN-1072 - a lot of folks don't use Ambari and have
their own deployment and cluster management solutions.
# I did not know about badblocks - I think, like smartctl, as long as the code
can handle the utility not being present I'm fine with adding support for it.
> Use smartctl to determine health of disks

> It would be nice to add support for smartctl(on machines where it is
> available) to determine disk health for the YARN local and log dirs(if
> smartctl is applicable). The current disk checking mechanism misses out on
> issues like bad sectors, etc.
