Hi, I am using storm 0.9.1-incubating on a single machine cluster to run a simple twitter hashtag extractor. I am using the Storm-twitter-workshop which i found to be extremely useful.
https://github.com/kantega/storm-twitter-workshop I have used this program before with storm 0.8.1 and it ran like a charm. I might mention that was on a server machine with quite 2 quad xeon processors. This time i am trying it on my laptop( i5 , 8GB). But i am constantly getting this error in the worker log files 2014-07-10 13:01:47 b.s.m.n.Client [INFO] Reconnect ... [24] 2014-07-10 13:01:58 b.s.m.n.Client [INFO] Reconnect ...

If i declare just one instance of the hashtag extractor Bolt it fails to get anything but for more that 1 it does manage to get me a few hashtags though with quite high latency. Another strange part related to this machine is if i declare more than 2 supervisor.slots.ports the program doesnt even launch any more showing some initialitzation error. Sorry if i blabbered a lot about the hardware and stuff. But somehow to me it seemed quite related to the problem. Any sort of help will be really useful. Thanks, Suparno
