Sean Owen resolved SPARK-20634.
-------------------------------
Resolution: Invalid
I can't understand what this is describing; please read
http://spark.apache.org/contributing.html . This doesn't specify any particular
problem. You would not expect k-means results to be the same each time. It's
stochastic.
> result of MLlib KMeans cluster is not stabilize
> -----------------------------------------------
>
> Key: SPARK-20634
> URL: https://issues.apache.org/jira/browse/SPARK-20634
> Project: Spark
> Issue Type: Bug
> Components: MLlib
> Affects Versions: 2.0.2
> Environment: Windows 10
> spark 2.0.2 standalone
> spyder 3.1.4
> Anaconda 4.3.0
> python 3.5.2
> Reporter: Simon.J
> Priority: Critical
>
> 1.Get a DataFrame through python with Cx_Oracle lib.
> 2.Start a local Spark Session.
> 3.Convert the dataset for Kmeansmodel train.
> 4.Train the KMeans model and predict the same data.just set K =3
> 5.Get the ClassifierFeature of the KMeans model'predict.
> 6.Get the count of every ClassifierFeature.
> 7.Loop 4-6 for 20 times.
> 8.Compare the result of every time.
> 9.Find the KMeans result dose not stabilize.
> 10.The same dataset and param for ML package'KMeans, its result is the same.
