Gilbert Song updated MESOS-7643:
--------------------------------
Priority: Major (was: Critical)
> The order of isolators provided in '--isolation' flag is not preserved and
> instead sorted alphabetically
> --------------------------------------------------------------------------------------------------------
>
> Key: MESOS-7643
> URL: https://issues.apache.org/jira/browse/MESOS-7643
> Project: Mesos
> Issue Type: Improvement
> Components: containerization
> Affects Versions: 1.1.2, 1.2.0, 1.3.0
> Reporter: Michael Cherny
> Assignee: James Peach
> Priority: Major
> Labels: isolation
>
> According to documentation and comments in code the order of the entries in
> the --isolation flag should specify the ordering of the isolators.
> Specifically, the `create` and `prepare` calls for each isolator should run
> serially in the order in which they appear in the --isolation flag, while the
> `cleanup` call should be serialized in reverse order (with exception of
> filesystem isolator which is always first).
> But in fact, the isolators provided in '--isolation' flag are sorted
> alphabetically.
> That happens in [this line of
> code|https://github.com/apache/mesos/blob/master/src/slave/containerizer/mesos/containerizer.cpp#L377].
> In this line use of 'set<string>' is done (apparently instead of list or
> vector) and set is a sorted container.
