      Dear FIWARE coach,
      we forward you a support request received from a CreatiFI applicant we are
      not able to solve.
      Please let us know if you need direct contact with the submitter.
      Thanks.

      *********************************

      We struggle getting a custom MapReduce job running with an external library.

      We can do the following:
      run the hadoop-examples.jar
      run the hadoop-examples.jar in our home directory
      run the hadoop word-count.jar example in our home directory

      We fail to run the following:
      run the hadoop word-count.jar with mahout: we get the following compiler
      error

      [jakob.zeitler@cosmosmaster-gi WordCountExample]$ javac -classpath
      "/usr/lib/hadoop-0.20/hadoop-0.20.2-cdh3u6-core.jar:/home/jakob.zeitler/lib/apache-mahout-distribution-0.10.1/:/home/jakob.zeitler/lib/apache-mahout-distribution-0.10.1/lib/"
      -d classes/ WordCount.java
      WordCount.java:12: cannot find symbol

      location: package org.apache
      import org.apache.mahout;
