Sahara source code contains non-free .jar blobs

[Thomas Goirand]

A simple command shows what's in the subject of this bug:

$ find . -iname '*.jar'
./etc/edp-examples/edp-spark/spark-example.jar
./etc/edp-examples/edp-spark/spark-wordcount.jar
./etc/edp-examples/edp-mapreduce/edp-mapreduce.jar
./etc/edp-examples/edp-java/edp-java.jar
./etc/edp-examples/hadoop2/edp-java/hadoop-mapreduce-examples-2.6.0.jar
./etc/edp-examples/edp-pig/trim-spaces/udf.jar
./sahara/plugins/mapr/services/swift/resources/jackson-core-asl-1.9.13.jar
./sahara/plugins/mapr/services/swift/resources/hadoop-swift-latest.jar
./sahara/plugins/mapr/services/swift/resources/jackson-mapper-asl-1.9.13.jar
./sahara/service/edp/resources/edp-spark-wrapper.jar
./sahara/service/edp/resources/edp-main-wrapper.jar

These files should be removed from the Sahara source code, as they are pre-built files, which have nothing to do in the source code of any project. In every downstream distribution (ie: Debian, Red Hat, or Ubuntu), this kinds of blobs makes the whole project non-free. So either build them from source (ie: java code), (build-)depend on them, or just remove them.
