[jira] [Created] (MAHOUT-1708) Replace Preconditions with asserts for Spark code

Pat Ferrel created MAHOUT-1708:
----------------------------------

             Summary: Replace Preconditions with asserts for Spark code
                 Key: MAHOUT-1708
                 URL: https://issues.apache.org/jira/browse/MAHOUT-1708
             Project: Mahout
          Issue Type: Bug
          Components: Hdfs, Math
    Affects Versions: 0.10.0
         Environment: Spark
            Reporter: Pat Ferrel
            Assignee: Andrew Musselman
             Fix For: 0.10.1


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.
