[jira] [Created] (SPARK-19066) SparkR LDA doesn't set optimizer correctly

Miao Wang created SPARK-19066:
---------------------------------

             Summary: SparkR LDA doesn't set optimizer correctly
                 Key: SPARK-19066
                 URL: https://issues.apache.org/jira/browse/SPARK-19066
             Project: Spark
          Issue Type: Bug
          Components: SparkR
            Reporter: Miao Wang


spark.lda pass the optimizer "em" or "online" to the backend. However, LDAWrapper doesn't set optimizer based on the value from R. Therefore, for optimizer "em", the `isDistributed` field should be TRUE.

In addition, the `summary` method should bring back the results related to `DistributedLDAModel`.
