How to set maxDF to pyspark.ml.feature.CountVectorizer even though there was no maxDF parameter?

My program was already working nicely using CountVectorizer from pyspark.ml package. But, this CountVectorizer doesn't have maxDF parameter like CountVectorizer in sklearn.feature_extraction.text package which remove term that appear too frequent in document list. Is there any way to apply that to CountVectorizer from pyspark.ml package?






python python-3.x apache-spark pyspark apache-spark-mllib

          maxDF Param has been included in Spark 2.4.0 (not released officially yet, but already available from PyPi and Apache Foundation archives):





          • SPARK-23166 - Add maxDF Parameter to CountVectorizer


          • SPARK-23615 - Add maxDF Parameter to Python CountVectorizer


          and can be used as any other Param:



          from pyspark.ml.feature import CountVectorizer
          

          
vectorizer = CountVectorizer(maxDF=99)


          or



          vectorizer = CountVectorizer().setMaxDF(99)


          To use it you'll have to either update Spark to 2.4.0 or later, or backport the corresponding PRs and build Spark from source.

                    0 I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem? Are there some restrictions to the Created User Group compared to BUILTINUsers? scheduled-tasks taskscheduler windowstaskschedule share | improve this question asked Nov 15 '18 at 15:36 Far...
