[jira] [Commented] (MESOS-6654) Duplicate image layer ids may make
the backend failed to mount rootfs.
[ https://issues.apache.org/jira/browse/MESOS-6654?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15844232#comment-15844232 ]

commit d261076edff66c6a22a47e9f46c425917394a1e3

Fixed duplicate image layer ids returned by docker store.
This issue is exposed by pulling the 'mesosphere/inky' docker
image using registry puller. Due to the duplicate layer id
from the manifest, there are duplicate layer pathes passed
to the backend. The aufs backend cannot handle this case and
returns 'invalid arguments' error. Ideally, we should make
sure that layer paths that are passed to the backend are
unique.

> Some images (e.g., 'mesosphere/inky') may contain duplicate layer ids in manifest, which may cause some backends unable to mount the rootfs (e.g., 'aufs' backend). We should make sure that each layer path returned in 'ImageInfo' is unique.
