-----------------------------------
Hi [~sunilg]
The patch overall looks good. Something I am not quite sure about
ResourceUtils has some other public methods, e.g getResourceTypesArray(), this
is used in DomainResourceFairnessPolicy to compute shares, would that cause
issue when the array has some non-countable resource?
Apart from that, can we add some UT for verification? E.g to create some
resource requests with such tag, verify the get methods as well as the
allocation result.
Thanks

> 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.
