I recently got to know about storm and I find it really interesting. I want to know what happens when a storm supervisor goes down.
I am going through the following article to play with storm a bit and get to know what's really going on. http://www.michael-noll.com/tutorials/running-multi-node-storm-cluster/ I successfully started zookeeper, nimbus, storm UI and a single supervisor. Also, I uploaded the WordCount topology in storm-starter example and got it running. I am monitoring this through the storm UI. However, when I kill my supervisor (using ctrl-c), I can see that all the emitted, transferred columns reset in the topology summary window in UI. When I restart the supervisor, it starts from zero. Does this mean that I have lost some of the state informations associated with my topology when the supervisor went down? Thanks in advance for any clarifications. Regards, Thilina
