How to build and Run Storm Topology within Intellij IDEA

Question

I followed Storm Starter instructions and imported Twitter Storm in IntelliJ. For sake of testing I edited ExclaimationToplogy a bit and used following Maven command to build and run it:

mvn -f m2-pom.xml compile exec:java -Dstorm.topology=storm.starter.ExclamationTopology

But I am more interested to build and run within IDE rather than from command line. What actions do I need to perform?

Thanks

Answer 1

1. Follow the steps in storm-starter's: Using storm-starter with IntelliJ IDEA
2. Open Maven's pom.xml file and remove <scope>provided</scope> line from storm dependency. This enables IntelliJ to compile storm dependency on build.
3. Go to /src/jvm/storm/starter/, right click on ExclamationTopology file and Run 'ExclamationTop....main()'

Answer 2

From within IntelliJ, if you get Clojure related compiler errors involving LocalCluster then .... do a mvn clean install -DskipTests from the command line on the same project first. Then do a 'Rebuild Project' from within IntelliJ. Life is full of mysteries :-).

You need to also ensure that the storm-core is not in provided scope for storm-starter.
