I am using TridentTopology to read from a file and emit aggregates using a single spout. When I have a single supervisor node, the topology is working fine and spout is emitting fine. However when a second supervisor node is added, the spout stops emitting. I was able to verify that there are two supervisor nodes using Storm UI. There are no errors either in supervisor log or worker log files on both the nodes.

To put it accurately, spout is emitting but the execute() method of class overriding BaseFunction is not getting executed. Also Storm UI does not show any tuples getting emitted. – Kishore Kopalle Jul 20 '13 at 19:37
