             Summary: Reintroduce image fetch deduplication while keeping it possible to destroy UCR containers in PROVISIONING state
                 Key: MESOS-10169
                 URL: https://issues.apache.org/jira/browse/MESOS-10169
             Project: Mesos
          Issue Type: Bug
            Reporter: Andrei Sekretenko


The fix for https://issues.apache.org/jira/browse/MESOS-9964 had to drop the image fetch deduplication that was introduced long ago in https://issues.apache.org/jira/browse/MESOS-3736. We should reintroduce the deduplication back.

UCR containers pulling the same image at the same time should pull the image only once.
*This deduplication should not prevent killing some of the PROVISIONING containers, and such killing should not interfere with provisioning of other containers.*

I would argue that it is OK for all the containers depending on a single image pull to hang if this single pull hangs.
