             Summary: RowEncoder should be documented and publicly accessable
                 Key: SPARK-17435
                 URL: https://issues.apache.org/jira/browse/SPARK-17435
             Project: Spark
          Issue Type: Improvement
            Reporter: Daniel Shields


The object org.apache.spark.sql.catalyst.encoders.RowEncoder is critical when constructing a Dataset that is not Dataset[Row] but still has Row in its type.  For example, consider the following:

df.map(row => (row.getInt(0), row))(Encoders.tuple(Encoders.scalaInt, RowEncoder(df.schema))

Alternatively, there could be a way to get the Encoder from Dataset directly; it's unclear why 'encoder' isn't a member of Dataset.
