Jian He commented on YARN-6347:
-------------------------------

How often does the store operation occur ? Is it on per-container basis ? If so, I think that will cause too much load.

> In YARN-6345 we introduce the notion of container tags.
> In this JIRA, we will create a service in the RM, similar to the Node Labels Manager, that will store the tags of each active container.
> Note that a node inherits the tags of all containers that are running on that node at each moment. Therefore, the container tags can be seen as dynamic node labels. The suggested service will allow us to efficiently retrieve the container tags of each node.
