-------------------------------
Issue Type: Improvement (was: Sub-task)
Parent: (was: HADOOP-12756)
> Phase I: Some improvement for incorporating Aliyun OSS file system
> implementation
> ---------------------------------------------------------------------------------
>
> Key: HADOOP-13377
> URL: https://issues.apache.org/jira/browse/HADOOP-13377
> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs
> Affects Versions: 2.8.0, HADOOP-12756
> Reporter: Genmao Yu
> Assignee: Genmao Yu
> Fix For: HADOOP-12756
>
>
> This work is based on
> [HADOOP-12756|https://issues.apache.org/jira/browse/HADOOP-12756].
> There are some stability problems which we should pay attention to, include
> but not limited to:
> 1. OSS will close long-time connection(> 3h) and idle connection(>1minute),
> while it is pretty common.
> 2. The 'copy' operation is time-consuming, so we could use the existing
> Job/Task executing logic, i.e. copy temp result from temp directory to final
> directory.
> and some hack optimization：
> 1. use double buffering and multi-thread when read oss data
> 2. data is split in chunk and uploaded in ‘multipart’ way
