Vibhay,
You are using master branch which is under development to
move to Java. This might be very unstable. I suggest you to
use 1.x-branch in general as its getting ready for storm
1.0 release. You don't need to add anything to storm.yaml ,
defaults should be fine for a single node cluster.
1. git checkout 1.x-branch
2. mvn -DskipTests clean install
3. cd storm-dist/binary
4. mvn clean package
5. cd target
6. find and unzip apache-storm-1.0.0-SNAPSHOT
7. run required services
bin/storm dev-zookeeper, bin/storm nimbus, bin/storm supervisor,
bin/storm ui
8. ./bin/storm jar
examples/storm-starter/storm-starter-topologies-1.0.0-SNAPSHOT.jar
org.apache.storm.starter.WordCountTopology wordcount
For bit more details you can refer here
http://blog.harsha.io/setting-up-a-single-node-apache-storm-cluster/
its on a older version of storm but relevant for the latest as well.
