With this change, the node request object must be up-to-date before it can be stored, which avoids outdated data being written to ZooKeeper. The purpose of this change is a bug in the node request handling which could reset the node request back to REQUESTED shortly after it was fulfilled by nodepool. The problem occurrs when revisedRequest() is called shortly after the node request was fulfilled by nodepool but the node request cache in the scheduler is not yet up-to-date. As the node is no longer locked by nodepool, reviseRequest() will update the data in ZooKeeper with the outdated information that is stored in the node request object. As a result the node request in ZooKeeper will be reset to REQUESTED although it was already set to FULFILLED by nodepool. In this case neither the scheduler nor nodepool seem to process the node request anymore. The scheduler thinks it's still in state REQUESTED and nodepool most probably takes note of the requests it has already handled. Change-Id: I713c8c442e2c4022ceaaa5486ee3ab2b359fbfdf
