FSDataOutputStream |
AbstractFileSystem.create(Path f,
EnumSet<CreateFlag> createFlag,
org.apache.hadoop.fs.Options.CreateOpts... opts)
The specification of this method matches that of
FileContext.create(Path, EnumSet, Options.CreateOpts...) except
that the Path f must be fully qualified and the permission is absolute
(i.e. |
FSDataOutputStream |
FileContext.create(Path f,
EnumSet<CreateFlag> createFlag,
org.apache.hadoop.fs.Options.CreateOpts... opts)
Create or overwrite file on indicated path and returns an output stream for
writing into the file.

AbstractFileSystem.createInternal(Path f,
EnumSet<CreateFlag> flag,
FsPermission absolutePermission,
int bufferSize,
short replication,
long blockSize,
Progressable progress,
org.apache.hadoop.fs.Options.ChecksumOpt checksumOpt,
boolean createParent)
The specification of this method matches that of
AbstractFileSystem.create(Path, EnumSet, Options.CreateOpts...) except that the opts
have been declared explicitly. |
void |
FileContext.createSymlink(Path target,
Path link,
boolean createParent)
Creates a symbolic link to an existing file.
|
void |
FilterFileSystem.createSymlink(Path target,
Path link,
boolean createParent) |
void |
FileSystem.createSymlink(Path target,
Path link,
boolean createParent)
|
abstract void |
AbstractFileSystem.mkdir(Path dir,
FsPermission permission,
boolean createParent)
The specification of this method matches that of
FileContext.mkdir(Path, FsPermission, boolean) except that the Path
f must be fully qualified and the permission is absolute (i.e. |
void |
FileContext.mkdir(Path dir,
FsPermission permission,
boolean createParent)
Make(create) a directory and all the non-existent parents.
|
void |
AbstractFileSystem.rename(Path src,
Path dst,
org.apache.hadoop.fs.Options.Rename... options)
The specification of this method matches that of
FileContext.rename(Path, Path, Options.Rename...) except that Path
f must be for this file system. |
void |
FileContext.rename(Path src,
Path dst,
org.apache.hadoop.fs.Options.Rename... options)
Renames Path src to Path dst
Fails if src is a file and dst is a directory.
|
abstract void |
AbstractFileSystem.renameInternal(Path src,
Path dst)
The specification of this method matches that of
FileContext.rename(Path, Path, Options.Rename...) except that Path
f must be for this file system and NO OVERWRITE is performed. |
void |
AbstractFileSystem.renameInternal(Path src,
Path dst,
boolean overwrite)
The specification of this method matches that of
FileContext.rename(Path, Path, Options.Rename...) except that Path
f must be for this file system. |
