    Hi @chobeat, thanks for pinging this issue. I forgot sending a discuss email to mailing
thread. I think we have to discuss about followings:
    * What is main purpose to support PMML? Is this feature for only model portability in
FlinkML? If not, we have to support other systems such as R or Spark MLlib.
    * What about FlinkML only format? I think that support for distributed system in PMML
is poor. XML-based format is hard to parallelize.
    I would like to create a general ML model importing/exporting framework. Then, we can
easily add the PMML support based on the framework.

> The predictive model markup language (PMML) [1] is a widely used language to describe
predictive and descriptive models as well as pre- and post-processing steps. That way it allows
and easy way to export for and import models from other ML tools.
