> Project: Hadoop Distributed Data Store
> Issue Type: Improvement
> Components: SCM
> Affects Versions: 0.2.1
> Reporter: Nanda kumar

> Priority: Major
> Fix For: 0.2.1

> Introducing {{NodeStateManager}} will make the lifecycle management of
> datanodes in SCM easy. NodeStateManager will be responsible for marking the
> datanodes as stale or dead when heartbeat is not received and it will
> maintain the current state of all the datanodes in the cluster.
> NodeStateManager should be the only place we maintain node state information,
> everyone else should use NodeStateManager to know about the state information.
