Resource State
Current status of the resource being used by a task instance. The Controller uses the same process each time it launches a task on a resource and the resource goes through the same series of states: 1 INITIAL The initial state. This is the default value at launch time. 2 REQUESTED When the task requests the resources it needs, the Resource state becomes Requested. 3 ACQUIRED When all of the requested resources are available and acquired by the server, the Resource state becomes Acquired. 4 RETURNED When the task completes, the server returns the resources it was using, and the Resource state becomes Returned.
