What does the term "first-class" mean in this sentence?
"We live in a flawed world, and Hadoop [computer software] is designed to survive in it by not only tolerating hardware and software failures, but also treating them as first-class conditions that happen regularly"
Websters defines first-class as being of the best quality, first-rate; as, a first-class telescope, or as in a first-class car.
However that traditional definition does not seem to fit, because I would not think of incidents of hardware failure events being of high or low quality.
Lets say my car breaks down while driving, we do not say the car failure was first-class.
