Hi [~shivaram], do we still need this? If so, I can maybe give a try.

> 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.
