> The pre-provisioned volume is specified as a resource, but such resource is different comparing to what is managed now in YARN, e.g memory, vcores. They are constrained by 3rd party storage systems, so it looks more like an unmanaged resource. In such case, we need to ignore the resource calculation over them in the resource calculators. This can be done based on the resource tags.
