Subject [jira] [Commented] (MESOS-6950) Launching two tasks with the same Docker image simultaneously may cause a staging dir never cleaned up
Date Thu, 19 Jan 2017 03:00:34 GMT

    [ https://issues.apache.org/jira/browse/MESOS-6950?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15829215#comment-15829215

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.

> 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}
