## What changes were proposed in this pull request? Description about pipeline in this paragraph is incorrect https://spark.apache.org/docs/latest/ml-pipeline.html#how-it-works > If the Pipeline had more **stages**, it would call the LogisticRegressionModel’s transform() method on the DataFrame before passing the DataFrame to the next stage. Reason: Transformer could also be a stage. But only another Estimator will invoke an transform call and pass the data to next stage. The description in the document misleads ML pipeline users. ## How was this patch tested? This is a tiny modification of **docs/ml-pipelines.md**. I jekyll build the modification and check the compiled document. Author: Zhe Sun <ymwdalex@gmail.com> Closes #17137 from ymwdalex/SPARK-19797-ML-pipeline-document-correction.
