> Convert Sqoop format to Parquet format via MapReduce

> Key: SQOOP-1390

>
> Parquet files keep data in contiguous chunks by column, appending new records
> to a dataset requires rewriting substantial portions of existing a file or
> buffering records to create a new file. So while Parquet may have storage and
> query benefits, it doesn't make sense to write to it directly from
> record-based tools. We'd consider to use Kite SDK to simplify the handling of
> Parquet specific things.
> The following listed the major areas for this:
> * Implement ParquetImportMapper
> * Hook up the ParquetOutputFormat and ParquetImportMapper in the import job.
