Hi, Thanks so much for helping so far! I did want you guys said about setting the embedded execution to be false and remove the input arguments. Here is what I got: [ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.5.0:java (default-cli) on project beam-examples-java: An exception occured while executing the Java class. null: InvocationTargetException: Failed to run: hadoop org.apache.beam.runners.apex.ApexYarnLauncher /tmp/beam-runner-apex1438316137710606714params (exit code 127) [ERROR] bash: hadoop: command not found [ERROR] -> [Help 1] If any of you would have further solution for this :( Claire

The console log only contains output from Maven. Is logging turned off (or a suitable slf4j backend missing)?

Do you see any output? In case it writes to files, anything in output or output staging directories?

In a separate terminal window, run "jps -lv" and look for the jvm process id that executes org.apache.beam.examples.TfIdf . Use jstack <process id> to get the stack trace.

However my terminal always get frozen when running the command: mvn compile exec:java -Dexec.mainClass=org.apache.be am.examples.TfIdf \ -Dexec.args="--inputFile=pom.x ml --output=counts --runner=ApexRunner" -Papex-runner Would anyone have solution for this?
