Description

The `MesosContainerizer` supports "host volumes". However, there is no specific volume type defined for "host volumes" (https://github.com/apache/mesos/blob/master/include/mesos/mesos.proto#L1921). Instead, the `MesosContainerizer` relies on inferring the mount paths from the "host_path" to decipher if the user wants a "host volume".

It would be better to be more explicit and have a volume source type of "HOST_VOLUME" in the volume types.
