Gilbert Song commented on MESOS-6950:
-------------------------------------
Thanks [~klueska].
[~qianzhang], thanks for finding the root cause. Correct, we should create the
staging dir inside of the pulling condition. The second staging dir you saw
should be an empty dir though. I will fix it, should be quick.
> Launching two tasks with the same Docker image simultaneously may cause a
> staging dir never cleaned up

> If user launches two tasks with the same Docker image simultaneously (e.g.,
> run {{mesos-executor}} twice with the same Docker image), there will be a
> staging directory which is for the second task never cleaned up, like this:
> {code}
> └── store
> └── docker
> ├── layers
> │ ...
> ├── staging
> │ └── a6rXWC
> └── storedImages
> {code}
