描述
ParquetOutputFormat should support custom OutputCommitter.
There is a need to bypass current Hadoop functionality of writing output data under **_temporary** folder. Especially with AWS S3, there can be huge overhead of moving the files from **_temporary** folder to output folder.

调研方向
从 ParquetOutputFormat 开始,检查 Hadoop 的 OutputCommitter 集成,然后阅读关于现有工作的 pull request #1361。完成的标准是能够支持自定义 committers,同时避免向 _temporary 进行不必要的写入以及在 S3 上移动文件。
