Lohit Vijayarenu commented on YARN-1383:
----------------------------------------
On big clusters logging for each heartbeat is too much. To debug if
NodeManagers are heartbeating, we could possibly use other methods like network
connection, stack traces and such. +1 on removing this line.
> Remove node updates from the Fair Scheduler event log
