Hi there, First of all, as this is my first message to the list, I'd like to thank you all for Storm, this project is impressive and is very interesting. I'm glad I found it for the new project I'm working on! It's a pleasure to learn how to master it.
Here comes my first questions. I've built a topology with a Spout that emits tweets from the "Sample" streaming API, using twitter4j. This is working fine, but every once in a while, I get an exception from twitter4j which results in an "unserializable exception" error showing up in my Storm UI (under the "last error" field). I'd like to catch that exception but I clearly have no clue where this can be caught. Anyone has an idea on the good way (if any) to catch exceptions in a Spout? Also, my Spout's stats remain empty (0 acked and 0 failed) no matter of my bolts activities (counters are updated perfectly for them). Is there any reason for that? I thought the stats for the Spout would be the sum of the bolts. Should I ack/fail tuples from the Spout itself? If so, it looks a bit complicated to implement, it would mean to keep a state somewhere between bolts and spout. Am I missing something?
