>             Project: Mesos
>          Issue Type: Bug
>    Affects Versions: 1.2.2, 1.3.1, 1.4.1

> The reason is because on Linux, if multiple containers in a default executor want to share a persistent volume, it'll use SANDBOX_PATH volume source with type PARENT. This will be translated into a bind mount in the nested container's mount namespace, thus not visible in the host mount namespace. Mesos UI operates in the host mount namespace.
> One potential solution for that is to create a symlink (instead of just a mkdir) in the sandbox. The symlink will be shadowed by the bind mount in the nested container, but in the host mount namespace, it'll points to the corresponding persistent volume.
