Eric Badger commented on YARN-7815:
-----------------------------------
[~miklos.szeg...@cloudera.com], yes I absolutely agree. If we can remove the
usercach bind-mount, then we should. I'm just not sure how easy/possible that
is going off of [~shaneku...@gmail.com]'s comment above on not being able to
make it read-only
> Mount the filecache as read-only in Docker containers

> Priority: Major

> 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.
