[jira] [Commented] (MESOS-7546) WAIT_NESTED_CONTAINER sometimes returns 404

    [ https://issues.apache.org/jira/browse/MESOS-7546?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16022051#comment-16022051 ] 

Jie Yu commented on MESOS-7546:
-------------------------------

A short term solution would be to not delete bookkeeping data structure for nested containers in composing containerizer.

> {{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
