             Summary: set the amout of explained variance as parameter of pyspark.ml.feature.PCA
                 Key: SPARK-38083
                 URL: https://issues.apache.org/jira/browse/SPARK-38083
             Project: Spark
          Issue Type: Wish
          Components: MLlib
    Affects Versions: 3.2.1
            Reporter: Nicola


As in [sklearn.decomposition.PCA|https://scikit-learn.org/stable/modules/generated/sklearn.decomposition.PCA.html], where:

if {{0 < n_components < 1}} select the number of components such that the amount of variance that needs to be explained is greater than the percentage specified by n_components

it would be useful to have a similar behavior with the k parameter in pyspark.ml.feature.PCA.
