There is a method `Option find(const Resources& targets) const;` 
which does different from what this function does. This method extracts the 
Resource object from Resources that matches the passed in Resource& by not 
comparing the num_consumers.
So, let us rename this to:
`Option locate(const Resource& that) const;`

Does it sound ok to you?

I think that supporting SHARE as add-on operations for resources that can be 
shared (but are not created as shared) is useful. Same argument for UNSHARE.
Keeping in mind that this feature is for sharing resources (not just sharing of 
persistent volumes), I feel that these 2 apis have a need to co-exist.

As stated in the design doc, this has been done to make implementation simpler. 
Resource is used quite extensively in code and hence it was easier to embed 
num_consumers in it.
I agree we can keep num_consumers as a hashmap, such as:
`hashmap consumers;` and expose it in a singleton or 
something like that such that multiple classes can have access to it, esp. the 
sorter, allocator and master.
However, the num_consumers vary based on its context. For example:
i) For role, it contains the total tasks within a specific role that master has 
assigned this resource. This is across frameworks.
ii) For framework, it contains the total tasks within a specific framework that 
master has assigned this resource.
iii) For slave, it contains the total tasks within a slave that master has 
assigned this resource (this should be same as (i) for persistent volumes).
etc...
So we would need to maintain multiple hashmaps to reflect this. Secondly, there 
needs to be a `hashmap::find` for every access to num_consumers which can be 
avoided if we embed it within Resource::ShareInfo.

Another point that has been raised is if we should reconsider and actually 
expose `num_consumerss` to frameworks since that would give a good idea for 
frameworks to know when a `DESTROY` can be issued. Note that the `DESTROY` is 
not guaranteed to succeed though since another framework of the same role might 
have issued a launch task using this resource in the mantime (and that is the 
reason we did not expose this in the first place). However, I think we can 
consider exposing this to frameworks if we feel that would provide frameworks 
with some meaningful information regarding possibility of DESTROY being 
successful. Note that the same issue exists with non-shareable persistent 
volumes as well, but the use case is not as bad since there can be only 1 task 
that can use the persistent volume.

include/mesos/mesos.proto (line 688)


I don't think this field belongs in the protobuf. If this information 
doesn't need to be communicated on the wire, the master can simply track it 
internally, and reconstruct it upon agent reregistration after master failover.



include/mesos/mesos.proto (lines 988 - 989)


I'm curious if we'll really need these operations? Might it be enough to 
simply make a persistent volume shareable when it's created? The same might be 
the case for other shareable resources as well.



include/mesos/resources.hpp (line 222)


I might recommend renaming this method, due to the ubiquitous `get()` 
method of the `Future` and `Option` types. Perhaps `find()` instead?

No. This just checks that we are comparing 2 resources that both have share set 
(for shareable resources), or niether have share set (for regular non-shareable 
resources). It does not mandate num_consumers to be equal.

No, since the passed Resource "that" needs to have share=true. If that is not 
the case, it is not a shared resource and hence cannot be unshared. If "that" 
is a shared resource, then it falls through to the call to 
`_getExistingConsumers(that)` where the logic for num_consumers==0 is done.

In `destroyable()`, check for `contains()` is done for non shareable resources. 
For shareable resources, we do a similar check in `_getExistingConsumers()` but 
extract the resource to ensure its num_consumers==0.
I think it covers both scenarios. Am I missing something?

{None} is when num_consumers is not set, and 0 is when num_consumers is set to 
0. We do not send or expect to receive num_consumers for shareable resources in 
Resources for all messages going between master <-> framework. This condition 
handles the scenario when Resource is logged at these points when num_consumers 
is not set. An example is when we log the offer received while running all our 
test frameworks.

We can but I think it is fine here as well, especially because shareable 
resources are supported for all resource types but enabled for persistent 
volumes right now. Except the check in `Option Resources::validate(const 
Resource& resource)`, I do not think there are any references to assert that 
only persistent volumes can be shared.
Also in future, when we do extend sharing of resources to other resource tyoes 
as well, we should be good to go here.

Review request for mesos and Adam B.


Summary (updated)
-

Support sharing of resources through reference counting of resources.


Bugs: MESOS-4431
https://issues.apache.org/jira/browse/MESOS-4431


Repository: mesos


Description (updated)
---

Added new Offer::Operation of SHARE and UNSHARE for resources.
Added ShareInfo within Resources protobuf to allow for sharing of resources
and keep track of consumers of such resources.
Shareable resources keeps track of its consumers and makes decision based on
that during task launch and task termination.
Allow DESTROY or UNSHARE for shared volumes only if reference count is 0.
