org.apache.hadoop.yarn.api.records.Container
Container represents an allocated resource in the cluster.

The ResourceManager is the sole authority to allocate any Container to applications. The allocated Container is always on a single node and has a unique {@link ContainerId}. It has a specific amount of {@link Resource} allocated.
It includes details such as:
- {@link ContainerId} for the container, which is globally unique.
- {@link NodeId} of the node on which it is allocated.
- HTTP uri of the node.
- {@link Resource} allocated to the container.
- {@link Priority} at which the container was allocated.
- {@link ContainerState} of the container.
- {@link ContainerToken} of the container, used to securely verify authenticity of the allocation.
- {@link ContainerStatus} of the container.
Typically, an ApplicationMaster receives the Container from the ResourceManager during resource-negotiation and then talks to the NodManager to start/stop containers.
