I have 9 node managers in my cluster and all of them are randomly exiting. I can see that suddenly java threads are pretty high which was not the case so far.
What could be the reason that all node managers randomly exit? Reiterating : not specific to one or two node managers.
Hey @Simran kaur. Could you post your yarn node managers logs errors? If its not showing any WARN|ERR messages, you can try to raise the log's level to DEBUG. BTW, how much Heap Size you've set?
