------------------------------
Summary: Convert Sqoop format to Parquet format via MapReduce
Key: SQOOP-1390
URL: https://issues.apache.org/jira/browse/SQOOP-1390
Project: Sqoop
Issue Type: Sub-task
Reporter: Qian Xu
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.
