------------------------------
Attachment: HDFS-11548-HDFS-7240.001.patch
> OZone: SCM: Add node pool management API
> ----------------------------------------

> Issue Type: Sub-task

>
> The idea is to group registered nodes into pools of fixed size (say 24 nodes
> per pool) so that the container allocation and report can all be handled
> independently on a pool basis by SCM.
> The initial patch will implement the following Node Pool API that
> 1) add node to a node pool
> 2) remove a node from a pool
> 3) get the pool name that a node belongs to
> 4) get all the pool names
> 5) get all nodes of a pool
> The integration with SCM container allocation can be all nodes in a single
> default pool upon registration. We will provide a CLI to manage multiple
> pools and support for pool definition file later.
