public class NativeS3FileSystem extends FileSystem
A FileSystem
for reading and writing files stored on
Amazon S3.
Unlike S3FileSystem
this implementation
stores files on S3 in their
native form so they can be read by other S3 tools.

Progressable progress)
This optional operation is not yet supported.
|
FSDataOutputStream |
create(Path f,
FsPermission permission,
boolean overwrite,
int bufferSize,
short replication,
long blockSize,
Progressable progress)
Opens an FSDataOutputStream at the indicated Path with write-progress
reporting.
|

delete(Path path)
Deprecated.
|
boolean |
delete(Path f,
boolean recursive)
Delete a file.
|
FileStatus |
getFileStatus(Path f)
Return a file status object that represents the path.
|
URI |
getUri()
Returns a URI whose scheme and authority identify this FileSystem.
|
Path |
getWorkingDirectory()
Get the current working directory for the given file system
|
void |
initialize(URI uri,
Configuration conf)
Called after a new FileSystem instance is constructed.
|
FileStatus[] |
listStatus(Path f)
If
f is a file, this method will make a single call to S3. |
boolean |
mkdirs(Path f,
FsPermission permission)
Make the given file and all non-existent parents into
directories.
|
FSDataInputStream |
open(Path f,
int bufferSize)
Opens an FSDataInputStream at the indicated Path.
|
boolean |
rename(Path src,
Path dst)
Renames Path src to Path dst.
|
void |
setWorkingDirectory(Path newDir)
Set the working directory to the given directory.

If f
is a file, this method will make a single call to S3.
If f
is a directory, this method will make a maximum of
(n / 1000) + 2 calls to S3, where n is the total number of
files and directories contained directly in f
.
