Hi, I'm trying to run a topology on EC2, but I'm observing the following strange issue:
Some workers stop processing after a few seconds, without any error in the worker log. For example, my topology consists of 3 workers and each worker is running on its own EC2 node. Two of them stop processing after a few seconds. But they have already processed several tuples successfully. I'm using only one spout and shuffleGrouping at all bolts. If I add more spouts then all workers keep processing, but the performance is very bad. Does anyone have a guess why this happens? The topology is currently running at: http://54.155.156.203:8080 Thanks! Martin
