Klint Finley tracking the origin of YARN:
Arun C. Murthy awoke to a phone call. It was 3 a.m., and an ad-targeting
application at Yahoo, where he was an engineer, was running at painfully
slow speeds. The culprit: a piece of software code that tapped into the open
source number-crunching platform Hadoop. Someone else had written the code,
but it was Murthy’s job to fix it.
Like many other brilliant things, YARN has been born or at least inspired by the hate of the status quo.
