> Key: SQOOP-1390
> URL: https://issues.apache.org/jira/browse/SQOOP-1390
> Project: Sqoop
> Issue Type: Sub-task
> Components: tools
> Reporter: Qian Xu
> Assignee: Qian Xu
> Fix For: 1.4.6
>
> Attachments: SQOOP-1390.patch
>
>
> 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.
> The JIRA proposes to add the possibility to import an individual table from a
> RDBMS into HDFS as a set of Parquet files. We will also provide a
> command-line interface with a new argument {{--as-parquetfile}}
> Example invocation:
> {{sqoop import --connect JDBC_URI --table TABLE --as-parquetfile --target-dir
> /path/to/files}}
> The major items are listed as follows:
> * Implement ParquetImportMapper
> * Hook up the ParquetOutputFormat and ParquetImportMapper in the import job.
> * Be able to support import from scratch or in append mode
> Note that as Parquet is a columnar storage format, it doesn't make sense to
> write to it directly from record-based tools. So we'd consider to use Kite
> SDK to simplify the handling of Parquet specific things.
