-----------------------------------------
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.
