Sean Owen commented on SPARK-26247:
-----------------------------------
I tend to think of this problem as about as solved as it will be by MLeap.
There just hasn't been a representation that 'rules them all', so a library to
translate Spark models is probably about as good as it gets. PMML is the best
shot at a format and it doesn't cover enough; PFA seems similar in this regard.
