Subject [jira] [Created] (HADOOP-12471) Support Swift file (> 5GB) continuious uploading where there is a failure

--------------------------------

             Summary: Support Swift file (> 5GB) continuious uploading where there is a
failure
                 Key: HADOOP-12471
                 URL: https://issues.apache.org/jira/browse/HADOOP-12471
             Project: Hadoop Common
          Issue Type: New Feature
          Components: fs/swift
    Affects Versions: 2.7.1
            Reporter: Chen He


Current Swift FileSystem supports file larger than 5GB. 
File will be chunked as large as 4.6GB (configurable). For example, if there is a 46GB file
"foo" in swift, 
Then the structure will look like:

foo/000001
foo/000002
foo/000003
...
foo/000010

User will not see those 00000x files if they don't specify. That means, if use do:
\> hadoop fs -ls swift://container.serviceProvidor/foo

It only shows:
dwr-r--r--    4.6GB    foo

However, in my test, if there is a failure, during uploading the foo file, the previous uploaded
chunks will be left in the object store. It will be good to support continuous uploading based
on previous leftover
