yuhao yang commented on SPARK-16240:
------------------------------------

This still does not resolve the issue when user invokes LDA.load(path). (I'm 
creating https://issues.apache.org/jira/browse/SPARK-16249 to allow that). Yet 
loading compatibility for estimator is of lower priority, I assume.

> model loading backward compatibility for ml.clustering.LDA

> After resolving the matrix conversion issue, LDA model still cannot load 1.6 
> models as one of the parameter name is changed.

> We can perhaps add some special logic in the loading code.
