[Fiware-creatifi-coaching] [CreatiFI Benelux Hub] Running a MapReduce job on COSMOS Hadoop GE with Mahout library

[Andrea Maestrini]

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 at 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
