Hi All!
Resently I read an article about facebook's corona https://www.facebook.com/notes/facebook-engineering/under-the-hood-scheduling-mapreduce-jobs-more-efficiently-with-corona/10151142560538920 they solved in mr1 pull based task assignment: task trackers send heartbeat to jobtracker and recive new tasks in respond. This approach wasted 10-20 seconds for each tasks. My question is about YARN: was this trouble solved in YARN or not? Best regards, Mezentsev Pavel
