Subject [jira] [Created] (MESOS-7546) WAIT_NESTED_CONTAINER sometimes returns 404
Date Mon, 22 May 2017 23:27:04 GMT
Gastón Kleiman created MESOS-7546:
-------------------------------------

             Summary: WAIT_NESTED_CONTAINER sometimes returns 404
                 Key: MESOS-7546
                 URL: https://issues.apache.org/jira/browse/MESOS-7546
             Project: Mesos
          Issue Type: Bug
          Components: containerization
            Reporter: Gastón Kleiman


{{WAIT_NESTED_CONTAINER}} sometimes returns 404s even though the nested container has already
exited and the parent task/executor is still running.

This happens when an agent uses more than one containerizer (e.g.,
 {{docker,mesos}}, {{WAIT_NESTED_CONTAINER}} and the exit status of the nested container has
already been checkpointed.

The root cause of this is a bug in the {{ComposingContainerizer}} in the following lines:
https://github.com/apache/mesos/blob/1c7ffbeb505b3f5ab759202195f0b946a20cb803/src/slave/containerizer/composing.cpp#L620-L628
