Doris Xin created SPARK-2599:
--------------------------------

             Summary: almostEquals mllib.util.TestingUtils does not behave as 
expected when comparing against 0.0
                 Key: SPARK-2599
                 URL: https://issues.apache.org/jira/browse/SPARK-2599
             Project: Spark
          Issue Type: Bug
          Components: MLlib
            Reporter: Doris Xin
            Priority: Minor


DoubleWithAlmostEquals.almostEquals, when used to compare a number with 0.0, 
would always produce an epsilon of 1 >> 1e-10, causing false failure when 
comparing very small numbers with 0.0.
