When following the guide in the storm-starter repo, I'm unable to actually run any topology- like the ExclamationTopology
.
mvn clean install -DskipTests=true
ran successfully, executed from the top level Storm repo, as did mvn package
at the storm-examples
level.
When I try to run storm jar target/storm-starter-2.0.0-SNAPSHOT.jar org.apache.storm.starter.ExclamationTopology
, I get the error:
Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/storm/topology/IRichSpout
I'm running OS X, Java version:
java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)
Maven version 3.3.9.
Does anyone have any ideas on why I'm getting this error and what I should change in my setup?

Edit:
After following the suggestions in the answers below of removing the scope
line from the pom.xml
, this error was gone, but replaced by:
Exception in thread "main" java.lang.ExceptionInInitializerError
Caused by: java.lang.RuntimeException: java.io.IOException: Found multiple defaults.yaml resources. You're probably bundling the Storm jars with your topology jar. [jar:file:/Users/zachary/apache-storm-0.10.0/lib/storm-core-0.10.0.jar!/defaults.yaml, jar:file:/Users/zachary/storm/examples/storm-starter/target/storm-starter-2.0.0-SNAPSHOT.jar!/defaults.yaml]
Final Edit:
For any future googler, I ended up not getting the storm-starter
examples running via the commandline on a LocalCluster
. I instead set up a new project with Maven, adding storm-core
as a dependency, following [this] (https://github.com/mbonaci/mbo-storm/wiki/Storm-setup-in-Eclipse-with-Maven,-Git-and-GitHub) general guide. Then, in Eclipse, I was able to import the right packages from storm
to do the examples, like ExclamationTopology
. I rewrote that class using the same imports (changed to import backtype.storm.Config
, etc). Then, running the file as is just works.
This quick Maven guide helps too.
To be little bit more precise with regard to Nick's answer.
In storm-starter/pom.xml
the dependency storm-core
is specified with scope "provided":
<dependency>
<groupId>org.apache.storm</groupId>
<artifactId>storm-core</artifactId>
<version>${project.version}</version>
<!--
Use "provided" scope to keep storm out of the jar-with-dependencies
For IntelliJ dev, intellij will load properly.
-->
<scope>${provided.scope}</scope>
</dependency>
If you run locally using LocalCluster
you need to include storm-core
as dependency with default scope "compile", ie, just remove the scope
tag, and run mvn -DskipTests package
in storm-starter
again.
