Couldn't find org.apache.thrift7.TBase class

Question

I am getting error while executing the topology using the following maven command :

mvn exec:java -Dexec.mainClass="com.test.newpackage.TopologyMain" -Dexec.args="resource/words.txt"

If i try using following command :

java -cp ./target/wordcount-0.0.1.jar:/usr/local/hadoop/storm/storm-0.8.1.jar:/usr/local/hadoop/storm/lib/*:/usr/local/hadoop/storm/conf/storm.yaml com.test.newpackage.TopologyMain resource/words.txt

It neither gives error nor output. Even after i submit the topology to storm using :

storm jar StormEclipse.jar com.test.newpackage.TopologyMain /resource/words.txt

This topology doesn't list on the ui(localhost:8080).

Please check the scope of the storm dependency. The example pom.xml suggested in storm wiki sets the scope to test. So when you execute with maven, It will fail to resolve storm dependencies.

Remove the test scope, if you want to run it through maven
