|
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. |
abstract FSDataOutputStream |
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. |

|
abstract void |
AbstractFileSystem.mkdir(Path dir,
FsPermission permission,
boolean createParent)
The specification of this method matches that of

|
void |
AbstractFileSystem.rename(Path src,
Path dst,
org.apache.hadoop.fs.Options.Rename... options)

f must be for this file system. |
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. |
