SCM has allocated them in the SCM namespace but the

possible.
2. If there are no allocated containers -- Then we find a Open

/**
* A container state manager keeps track of container states and returns
* containers that match various queries.
* <p>
* This state machine is driven by a combination of server and client actions.
* <p>
* This is how a create container happens: 1. When a container is created, the
* Server(or SCM) marks that Container as ALLOCATED state. In this state, SCM
* has chosen a pipeline for container to live on. However, the container is not
* created yet. This container along with the pipeline is returned to the
* client.
* <p>
* 2. The client when it sees the Container state as ALLOCATED understands that
* container needs to be created on the specified pipeline. The client lets the
* SCM know that saw this flag and is initiating the on the data nodes.
* <p>
* This is done by calling into notifyObjectCreation(ContainerName,
* BEGIN_CREATE) flag. When SCM gets this call, SCM puts the container state
* into CREATING. All this state means is that SCM told Client to create a
* container and client saw that request.
* <p>
* 3. Then client makes calls to datanodes directly, asking the datanodes to
* create the container. This is done with the help of pipeline that supports
* this container.
* <p>
* 4. Once the creation of the container is complete, the client will make
* another call to the SCM, this time specifing the containerName and the
* COMPLETE_CREATE as the Event.
* <p>
* 5. With COMPLETE_CREATE event, the container moves to an Open State. This is
* the state when clients can write to a container.
* <p>
* 6. If the client does not respond with the COMPLETE_CREATE event with a
* certain time, the state machine times out and triggers a delete operation of
* the container.
* <p>
* Please see the function initializeStateMachine below to see how this looks in
* code.
* <p>
* Reusing existing container :
* <p>
* The create container call is not made all the time, the system tries to use
* open containers as much as possible. So in those cases, it looks thru the
* list of open containers and will return containers that match the specific
* signature.
* <p>
* Please note : Logically there are 3 separate state machines in the case of
* containers.
* <p>
* The Create State Machine -- Commented extensively above.
* <p>
* Open/Close State Machine - Once the container is in the Open State,
* eventually it will be closed, once sufficient data has been written to it.
* <p>
* TimeOut Delete Container State Machine - if the container creating times out,
* then Container State manager decides to delete the container.
