Shane Kumpf commented on YARN-7815:
-----------------------------------
Attached a patch that implements the proposal. Given I had to touch a bulk of
the test methods in {{TestDockerContainerRuntime}}, I went ahead a cleaned up
some warnings and unused code as well. If you'd prefer that clean up be moved
to a separate patch, I can do so.
> Mount the filecache as read-only in Docker containers

> 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.
