Miklos Szegedi commented on YARN-6345:
--------------------------------------
bq. How would it simplify the CLC though?
There is no need to add another proto entry for container configs next to
container tags and the propagation logic can be the same as well.
> Add container tags to resource requests

> This JIRA introduces the notion of container tags.
> When an application submits container requests, it is allowed to attach to
> them a set of string tags. The corresponding resource requests will also
> carry these tags.
> For example, a container that will be used for running an HBase Master can be
> marked with the tag "hb-m". Another one belonging to a ZooKeeper application,
> can be marked as "zk".
> Through container tags, we will be able to express constraints that refer to
> containers with the given tags.
