MapReduce WordCount Example for HDP 2.4.2
This repo contains a sample wordcount application compiled against Hortonworks HPD 2.4.2.
Verify everything works using:
mvn compile
Run the tests:
mvn test
Generate a jar package:
mvn package
The generated jar file will be located under the target directory
You can also generate a jar package skipping the tests phase:
mvn package -Dmaven.test.skip
If using an IDE like Eclipse or Intellij it can be useful to have the accompanying JavaDoc and source code while developing:
# Download sources and javadoc
mvn dependency:sources
mvn dependency:resolve -Dclassifier=javadoc
# Attach them to the project
mvn eclipse:eclipse
# Or if you are using Intellij
mvn idea:idea
