--------------------------------------
[~Elie A.] Thanks for your feedback! This JIRA is to discuss the pipeline API
but not specific components. For text preprocessing, we will certainly add
standard stemmer and stop words filter as transformers. There is also a
RegexTokenizer in review: https://github.com/apache/spark/pull/4504
> How to improve the current ML pipeline API?

> I created this JIRA to collect feedbacks about the ML pipeline API we

> create sub-tasks for each major issue.
