Hey,

I found a typo on page 141. In one of the annotations for Figure 6.8 (the one on the top right), it reads "tunning" instead "tuning". I also wanted to use this opportunity to tell you that this is a great book and an invaluable resource for my daily work.

Best wishes,

Raffael

In the 4.5 Listing in the book the Spout is changed from extending BaseBasicBolt to BaseRichBolt

I'm using storm snapshot 0.11 so i do not know if the issues I found are just with this version:

The listing states:
@Override
public void execute(Tuple tuple,
BasicOutputCollector outputCollector)

should be:

@Override
public void execute(Tuple tuple)

As the OutputCollector was already provided in the prepare()

Best Regards,
Gustavo

Page 52, Listing 3.8.

The build method should be static if invoked like in Listing 3.9:

public static StormTopology build(){...}
