Greetings, I have been trying different things to get a working giraph install. The most recent attempt is the following: I installed oracle java jdk 1.8.0 and maven 3.2.3 the installed hadoop 2.5.1. The hadoop install works. I then cloned the giraph repository from https://github.com/apache/giraph.git <https://github.com/apache/giraph> and tried to use
mvn package -Phadoop_yarn -Dhadoop.version=2.5.1 -DskipTests clean install But i get the following: [INFO] --- munge-maven-plugin:1.0:munge (munge) @ giraph-core --- Cannot write to file /usr/local/giraph/giraph-core/target/munged/main/com/yammer/metrics/core/NoOpTimer.java [INFO] ------------------------------------------------------------------------ [INFO] Reactor Summary: [INFO] [INFO] Apache Giraph Parent ...............................
