Qian Zhang commented on MESOS-6215:
-----------------------------------
That is because we wrongly cut the {{.wh.}} from {{.wh..wh..opq}} with
{{substr()}} in Mesos provisioner's code:
https://github.com/apache/mesos/blob/1.0.1/src/slave/containerizer/mesos/provisioner/provisioner.cpp#L359:L360
> Add support for opaque whiteout (.wh..wh..opq) in provisioner

> In a Docker image, there can be a opaque whiteout entry (a file with the name
> {{.wh..wh..opq}}) under a directory which indicates all siblings under that
> directory should be removed. But currently Mesos provisioner does not support
> to handle such opaque whiteout entry which will cause launching container
> with some Docker images fails, e.g.:
> {code}
> $ sudo src/mesos-execute --master=192.168.122.171:5050 --name=test
> --docker_image=rabbitmq --command="sleep 100"
