Yanbo Liang commented on SPARK-16000:
-------------------------------------
We should only add for models which support save/load in Spark 1.6. Since we do
not have save/load backward compatible test framework currently, we can only do
offline test right now. If this make sense, I can work on this issue.
> Make model loading backward compatible with saved models using old vector
> columns
