Manish Mishra commented on SPARK-16765:
---------------------------------------

You are right [~bryanc] There was one use case we are trying to build a 
pipeline for K Means in which were a using transformers for indexing and create 
vectors for categorical features before predicting on K-means. We were able to 
built it and I think it would be an example for another ML algorithm for 
Pipeline API. If you think the example added in the PR is redundant as an 
example for Pipeline, please close this issue. Thanks!

> A pipeline API example for K Means would be nicer to have in examples package 
> since it is one of the widely used ML algorithms. A pipeline API example of 
> Logistic Regression is already added to the ml example package.
