Qian Zhang commented on MESOS-9475:
-----------------------------------
Actually the task has the write permission to the root dir of the PV since we
change the owner of the PV's root dir to the task user in `filesystem/linux`
isolator, but we just do the `chown` for the root dir rather than recursively
for all the sub-dirs/files in the PV, so that's why the task cannot write to
the sub-dir which is still owned by root.
> Task launched with non-root user cannot write to existing sub-dirs/files in
> persistent volume

> Key: MESOS-9475
> URL: https://issues.apache.org/jira/browse/MESOS-9475
> Project: Mesos
> Issue Type: Bug
> Reporter: Qian Zhang
> Priority: Major
>
> Reproduce steps:
> 1. Create a PV via `/master/create-volumes`.
> 2. Log into the agent host with root and manually create a sub-dir under the
> PV.
> 3. Launch a task with a non-root user to touch a file under that sub-dir in
> the PV.
> The task failed because it has no write permission to the sub-dir.
