org.apache.hadoop.fs.s3 |
A distributed, block-based implementation of
FileSystem that uses Amazon S3
as a backing store. |

Modifier and Type | Field and Description |
---|---|
static FsPermission |
FileContext.DEFAULT_PERM
Default permission for directory and symlink
In previous versions, this default permission was also used to
create files, so files created end up with ugo+x permission.
|
static FsPermission |
FileContext.DIR_DEFAULT_PERM
Default permission for directory
|
static FsPermission |
FileContext.FILE_DEFAULT_PERM
Default permission for file
|

FileStatus.getPermission()
Get FsPermission associated with the file.

static FSDataOutputStream |
FileSystem.create(FileSystem fs,
Path file,
FsPermission permission)
create a file with the provided permission
The permission of the file is set to be the provided permission as in
setPermission, not permission&~umask
It is implemented using two RPCs.
