So when adding the mapr dependency, it pulls the following MapR specific
files:
```
./hadoop-hdfs-2.3.0-mapr-4.0.0-FCS.jar
./zookeeper-3.4.5-mapr-1401.jar
./hadoop-annotations-2.3.0-mapr-4.0.0-FCS.jar
./hadoop-common-2.3.0-mapr-4.0.0-FCS.jar
./hadoop-auth-2.3.0-mapr-4.0.0-FCS.jar
./maprfs-2.3.0-mapr-4.0.0-FCS.jar
```
I think the regular hadoop dependencies with `mapr` versions are fine, but
I'm not quite sure about the `maprfs` package. The contained namespaces are not
`org.apache.` but `com.mapr`.
Sadly, non of the license tags inside the `pom.xml` is stating anything
about the license.
http://repository.mapr.com/nexus/content/repositories/mapr-public/com/mapr/hadoop/maprfs/2.3.0-mapr-4.0.0-FCS/
So I will not add a MapR distribution for the 0.6 release to our download
page. The licensing situation is just too uncertain. I'll ask on their user's
forum.
