> YARN-1461 adds the concept of *Application Tags* to Yarn applications. In
> particular, a user is able to annotate application with multiple tags to
> classify apps. We can leverage this to define application namespaces based on
> application tags for placement constraints.
> Below is a typical use case.
> There are a lot of TF jobs running on Yarn, and some of them are consuming
> resources heavily. So we want to limit number of PS on each node for such BIG
> players but ignore those SMALL ones. To achieve this, we can do following
> steps:
> # Add application tag "big-tf" to these big TF jobs
> # For each PS request, we add "ps" source tag and map it to constraint
> "{color:#d04437}notin, node, tensorflow/ps{color}" or
> "{color:#d04437}cardinality, node, tensorflow/ps{color}{color:#d04437}, 0,
> 2{color}" for finer grained controls.
