Yanbo Liang commented on SPARK-9695:
------------------------------------

[~josephkb]
I agree to make HasSeed the main API to decide whether an algorithm takes a 
seed.
I propose to make PipelineStage extends from HasSeed and all meta-algs will get 
the same seed and can have reproducible results for entire pipelines. Please 
correct me if I have some misunderstands.
