------------------------------------------

             Summary: PySpark ML shouldn't use circular imports
                 Key: SPARK-19467
                 URL: https://issues.apache.org/jira/browse/SPARK-19467
             Project: Spark
          Issue Type: Improvement
          Components: ML, PySpark
    Affects Versions: 2.1.0, 2.0.0, 2.2.0
            Reporter: Maciej Szymkiewicz
            Priority: Minor


{{pyspark.ml}} and {{pyspark.ml.pipeline}} contain circular imports with the [former one|https://github.com/apache/spark/blob/39f328ba3519b01940a7d1cdee851ba4e75ef31f/python/pyspark/ml/__init__.py#L23]:

{code}
from pyspark.ml.pipeline import Pipeline, PipelineModel
{code}

and the [latter one|https://github.com/apache/spark/blob/39f328ba3519b01940a7d1cdee851ba4e75ef31f/python/pyspark/ml/pipeline.py#L24]:

{code}
from pyspark.ml import Estimator, Model, Transformer
{code}

This is unnecessary and can cause failures when working with external tools.
