I intend to run two instances of middleManagers on the same node. But my tasks are failing randomly i.e not all tasks are failing.
Failing tasks contains only GC output in their logs.
It was working fine when I ran 8 workers on the same node with single instance of middleManager but now I’m running 2 instances of middle-managers with worker capacity 4 each.
What could be the possible reason behind this.
