Gilbert Song created MESOS-8688:
-----------------------------------
Summary: Persistent volumes under taskgroup may not be writable
due to executor user under root.
Key: MESOS-8688
URL: https://issues.apache.org/jira/browse/MESOS-8688
Project: Mesos
Issue Type: Bug
Components: executor
Reporter: Gilbert Song
If the executor and the task are with different users, the persistent volume
may not be writable. For example, in the case of the default executor consuming
persistent volumes, if the executor is root user (from the frameworkinfo) and
the task is non-root user (from the commandinfo), the persistent volume would
be owned by the root which is unwritable for the task.
This is caused by the persistent volume support for nested container with the
default executor is a workaround (rely on the default executor specifying a
sandbox_path volume). We should figure out a correct way to support persistent
volume primitive for nested containers.
