@rawkintrevo Thanks for the explanation. Approach 1 to lower the barrier
and keep maintenance minimum make sense.

Check dependency tree with `mvn package dependency:tree` command
**Dependency confliction**
Following dependency versions are different from dependency brought by
Spark.
Mahout
```
com.esotericsoftware.kryo:kryo:jar:2.24:compile
com.fasterxml.jackson.core:jackson-core:jar:2.7.2:compile
```
Spark (1.6)
```
com.esotericsoftware.kryo:kryo:jar:2.21:compile
com.fasterxml.jackson.core:jackson-core:jar:2.4.4:compile
```
Can all conflicted dependencies be excluded ?
**Packaging**
If mahout requires to be loaded in spark executor's classpath, then adding
mahout dependency in pom.xml will not be enough to work with Spark cluster.
Could you clarify if mahout need to be loaded in spark executor?
