> While picking the datanode or the pool to place a container, SCM needs to be
> able to compare pools and datanodes. This jira proposes to add a Comparable
> Metric interface from which DatanodeCapacity and DatanodeIOLoad metrics can
> be derived. This will also convert SCM Container Placement Capacity policy to
> use these metrics.
> Adding these metrics makes all placement policy operate on the basis of these
> metrics and it makes it easy to simulate cluster imbalances as well as reason
> about code. All new SCM metrics which have the property of total ordering
> should be derived from this interface.
