>             Project: Hadoop Common
>          Issue Type: Sub-task
>          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
