Eric Yang commented on YARN-7815:
---------------------------------
I agree with [[email protected]]'s view point that keeping Read-only
for 2, 3 and remove 4. This gives a way to localize hadoop config and prevent
user to modify a read-only config. I also agree with [~jlowe] 's use case
where intermediate output is stored in container directory to evenly distribute
IO to separate disks instead of docker container tmp space. I think we have
consensus on 1 read-only, 4 removed. It would be nice to make 2, 3
controllable via config base on usage type.

> Currently, when using the Docker runtime, the filecache directories are
> mounted read-write into the Docker containers. Read write access is not
> necessary. We should make this more restrictive by changing that mount to
> read-only.
