> all use of guava has been removed from the code used with Spark except the use of Preconditions. These are pretty easy to replace.
> 1) remove guava from mahout-math, mahout-hdfs, poms and the spark dependency-reduced assembly.
> 2) you will now get compile errors for math and hdfs so remove the imports and replace and Preconditions with asserts.
> Not sure how many errors in replacing these will be caught with unit tests so be careful.
