--------------------------------------------------------------

When building Mahout against spark 2.0.2 I get one warning
```
[WARNING] /home/rawkintrevo/gits/mahout-local/spark/src/test/scala/org/apache/mahout/sparkbindings/drm/DrmLikeSuite.scala:127: warning: constructor SQLContext in class SQLContext is deprecated: Use SparkSession.builder instead
[WARNING]     val sqlContext= new org.apache.spark.sql.SQLContext(sc)
```

And then in the tests a lot of whining about 
```
Exception encountered when invoking run on a nested suite - requirement failed: MAHOUT_HOME is required to spawn mahout-based spark jobs *** ABORTED ***
  java.lang.IllegalArgumentException: requirement failed: MAHOUT_HOME is required to spawn mahout-based spark jobs
```


Hard to say for sure because I had to skip the tests re: above issue, but if you DskipTests, mahout compiles up until the shell. Taking the resulting jars to zeppelin and running some basic funtions checks like linear regression- it seems to work.
