I'm using Apache Storm 0.9.4. I set up a 5 nodes cluster and it works fine. (Actually 5 supervisors are working as docker containers on 5 different physical nodes.)
My environment is here
$cat /etc/redhat-release
CentOS release 6.6 (Final)
$docker -v
Docker version 1.4.1, build 5bc2ff8/1.4.1
$java -version
java version "1.7.0_79" OpenJDK Runtime Environment
(rhel-2.5.5.1.el6_6-x86_64 u79-b14) OpenJDK 64-Bit Server VM (build
24.79-b02, mixed mode)
Next, I create a maven project to submit a topology using Netbeans.
There are 1 topology and 1 spout.(very simple)
- MyTopology.java
- LoggerSpout.java
MyTopology works fine without GSON.
But, after I added Gson gson = new Gson(); in the nextTuple() function,
I got java.lang.NoClassDefFoundError: com/google/gson/Gson.
Here is what I did
-
1. mvn clean -> mvn compile -> mvn package -> BUILD SUCCESSFULY
2. storm jar ~/Desktop/teststorm/target/teststorm-1.0.jar jp.soushi.teststorm.MyTopology -> Submitting is OK.

- I checked the topology using Storm Web UI. After a while, I got NoClassDefFoundError.
- I edited nimbus.yaml, and add

Here is the error log(worker-6727.log).

I found this answer. But I don't understand well. java.lang.NoClassDefFoundError: com/google/gson/Gson
I also read these answers.
- Getting java.lang.ClassNotFoundException: com.google.gson.Gson for maven project
- GSON is not being imported into the maven pproject
- http://www.ciiycode.com/0JSJ6PgUXWxq/javalangnoclassdeffounderror-comgooglegsongsonbuilder-error
I spend 3 days to solve that... I have no idea. Can anyone provide any solution to this.Thanks in advance.
