Ray Chiang commented on YARN-5274:
----------------------------------
One question:
# [~vvasudev], do you think this should be organized as a subtask of YARN-5078?
Two comments:
# I was thinking about making this an example or option within YARN-1072.
# There's also a {{badblocks}} command available under Linux. I'm not sure how
common or easily available it is, but it could also be handy, depending on what
data we gather/store.
> 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.
