----------------------------------

             Summary: model loading backward compatibility for ml.clustering.LDA
                 Key: SPARK-16240
                 URL: https://issues.apache.org/jira/browse/SPARK-16240
             Project: Spark
          Issue Type: Bug
            Reporter: yuhao yang
            Priority: Minor


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

https://github.com/apache/spark/pull/12065

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