[jira] [Created] (SPARK-30678) Eliminate warnings from deprecated
BisectingKMeansModel.computeCost
Maxim Gekk created SPARK-30678:
----------------------------------
Summary: Eliminate warnings from deprecated BisectingKMeansModel.computeCost
Key: SPARK-30678
URL: https://issues.apache.org/jira/browse/SPARK-30678
Project: Spark
Issue Type: Sub-task
Components: SQL
Affects Versions: 3.0.0
Reporter: Maxim Gekk
The computeCost() method of the BisectingKMeansModel class has been deprecated. That causes warnings while compiling BisectingKMeansSuite:
{code}
[warn] /Users/maxim/proj/kmeans-computeCost-warning/mllib/src/test/scala/org/apache/spark/ml/clustering/BisectingKMeansSuite.scala:108: method computeCost in class BisectingKMeansModel is deprecated (since 3.0.0): This method is deprecated and will be removed in future versions. Use ClusteringEvaluator instead. You can also get the cost on the training dataset in the summary.
[warn] assert(model.computeCost(dataset) < 0.1)
[warn] ^
[warn] /Users/maxim/proj/kmeans-computeCost-warning/mllib/src/test/scala/org/apache/spark/ml/clustering/BisectingKMeansSuite.scala:135: method computeCost in class BisectingKMeansModel is deprecated (since 3.0.0): This method is deprecated and will be removed in future versions. Use ClusteringEvaluator instead. You can also get the cost on the training dataset in the summary.
[warn] assert(model.computeCost(dataset) == summary.trainingCost)
