[jira] [Created] (SPARK-6825) Data sources implementation to support `sequenceFile`

Shivaram Venkataraman created SPARK-6825:
--------------------------------------------

             Summary: Data sources implementation to support `sequenceFile`
                 Key: SPARK-6825
                 URL: https://issues.apache.org/jira/browse/SPARK-6825
             Project: Spark
          Issue Type: New Feature
          Components: SparkR, SQL
            Reporter: Shivaram Venkataraman


SequenceFiles are a widely used input format and right now they are not supported in SparkR. 

It would be good to add support for SequenceFiles by implementing a new data source that can create a DataFrame from a SequenceFile. However as SequenceFiles can have arbitrary types, we probably need to map them to User-defined types in SQL.
