-----------------------------
Summary: Mesos containerizer should run isolate() sequentially.
Key: MESOS-8083
URL: https://issues.apache.org/jira/browse/MESOS-8083
Project: Mesos
Issue Type: Improvement
Components: containerization
Reporter: Yan Xu
Currently all the isolate() calls to all isolators are done in parallel, unlike
prepare() and destroy(), which are done sequentially.
The following comment was provided as justification:
https://github.com/apache/mesos/blob/615f1f0bcdfab4df264f37d2ebf528da2e6aa426/src/slave/containerizer/mesos/containerizer.cpp#L1894-L1907
{noformat:title=}
// Isolate the executor with each isolator.
// NOTE: This is done is parallel and is not sequenced like prepare
// or destroy because we assume there are no dependencies in
// isolation.
{noformat}
However this is not strictly true, especially it's uncertain for isolator
modules. To be safe we should just handle it consistently with other isolator
calls and make it sequential.
