             Summary: 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: uncleGen
             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.
