Yanbo Liang commented on SPARK-16240:
-------------------------------------
Since we did not back port https://github.com/apache/spark/pull/12065 to 1.6,
we need to implement our own {{LDA.load}} with special handling for param
{{topicDistribution}} and replace it with {{topicDistributionCol}} when setting
params.
> 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.
