writing into the file.
|
FSDataOutputStream |
AbstractFileSystem.create(Path f,
EnumSet<CreateFlag> createFlag,
org.apache.hadoop.fs.Options.CreateOpts... opts)
The specification of this method matches that of

that the Path f must be fully qualified and the permission is absolute
(i.e. |

FileStatus |
AbstractFileSystem.getFileLinkStatus(Path f)
The specification of this method matches that of
