Jaeboo Jeong commented on YARN-4595:
------------------------------------
If I want to use multiple mounts(e.g. /dir1:/targerdir1,/dir2:/targetdir2), it
couldn't assign variables correctly.
Because during setting environment variables from input string(at Apps.java),
the comma is used for separator.
example
{code}mapreduce.map.env="YARN_CONTAINER_RUNTIME_TYPE=docker,YARN_CONTAINER_RUNTIME_DOCKER_IMAGE=hadoop-docker,YARN_CONTAINER_RUNTIME_DOCKER_LOCAL_RESOURCE_MOUNTS=/dir1:/targetdir1,/dir2:/targetdir2"{code}
> Add support for configurable read-only mounts when launching Docker containers

> Mounting files or directories from the host is one way of passing
> configuration and other information into a docker container. We could allow
> the user to set a list of mounts in the environment of ContainerLaunchContext
> (e.g. /dir1:/targetdir1,/dir2:/targetdir2). These would be mounted read-only
> to the specified target locations.
> Due to permissions and user concerns, for this ticket we will require the
> mounts to be resources that are in the distributed cache.
