> pyspark.mllib.clustering.LDAModel has no way to estimate the topic
> distribution for new documents. However, this functionality exists in
> org.apache.spark.mllib.clustering.LDAModel. This change would only require
> setting up the API calls. I have forked the spark repo and implemented the
> changes locally
