Rohith Sharma K S commented on YARN-3979:
-----------------------------------------

Thanks for the information!!
bq. NodeManager in one times all lost and recovery for a monment
I can think of the scenario very close to YARN-3990. Since you have 2 lakh apps completed
and 1600 NodeManager, when the all the nodes lost and reconnected, the number of events that
generated are {{(2lakh completed + 550 running = 200550)*1600(number of NodeManager) = 320880000}}
events..Ooops!!!
