Peng Meng commented on SPARK-17207:
-----------------------------------
Hi, org.apache.spark.ml.feature.CountVectorizerSuite.CountVectorizer can not
pass this PR.
Because org.scalatest.exceptions.TestFailedException: Expected
(2,[0,1],[1.0,1.0]) and (3,[0,1],[1.0,1.0]) to be within 1.0E-14 using absolute
tolerance for all elements.
The size of this two vectors is not the same, so it throws exception.
Should we fix this PR or fix CountVectorizerSuite?
> Comparing Vector in relative tolerance or absolute tolerance in UnitTests
> error

> The result of compare two vectors using UnitTests
> (org.apache.spark.mllib.util.TestingUtils) is not right sometime.
> For example:
> val a = Vectors.dense(Arrary(1.0, 2.0))
> val b = Vectors.zeros(0)
> a ~== b absTol 1e-1 // the result is true.
