> We’ve observed in LinkedIn execution environments that, all the monitors running on the YARN node-manager machines hitting an external service at the same time based upon the configured monitor scheduling interval.
> To eliminate unnecessary monitor execution spike and congestion caused to an external service at the same time, it’s essential to add a random jitter to the monitor scheduling interval.
> Random jitter will be added to monitor scheduling interval based upon a boolean monitor configuration
> Creating this ticket for book-keeping purposes to track these changes.
