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.
|
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. umask has been applied). |
FSDataOutputStream |
FileSystem.create(Path f,
FsPermission permission,
EnumSet<CreateFlag> flags,
int bufferSize,
short replication,
long blockSize,
Progressable progress)
Create an FSDataOutputStream at the indicated Path with write-progress
reporting.
|
FSDataOutputStream |
FilterFileSystem.create(Path f,
FsPermission permission,
EnumSet<CreateFlag> flags,
int bufferSize,
short replication,
long blockSize,
Progressable progress,
org.apache.hadoop.fs.Options.ChecksumOpt checksumOpt) |
FSDataOutputStream |
FileSystem.create(Path f,
FsPermission permission,
EnumSet<CreateFlag> flags,
int bufferSize,
short replication,
long blockSize,
Progressable progress,
org.apache.hadoop.fs.Options.ChecksumOpt checksumOpt)
Create an FSDataOutputStream at the indicated Path with a custom
checksum option
|
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. |

RawLocalFileSystem.createNonRecursive(Path f,
FsPermission permission,
EnumSet<CreateFlag> flags,
int bufferSize,
short replication,
long blockSize,
Progressable progress) |
FSDataOutputStream |
FilterFileSystem.createNonRecursive(Path f,
FsPermission permission,

FSDataOutputStream |
FileSystem.createNonRecursive(Path f,
FsPermission permission,
EnumSet<CreateFlag> flags,
int bufferSize,
short replication,

protected FSDataOutputStream |
FilterFileSystem.primitiveCreate(Path f,
FsPermission absolutePermission,
EnumSet<CreateFlag> flag,
int bufferSize,
short replication,
long blockSize,
Progressable progress,
org.apache.hadoop.fs.Options.ChecksumOpt checksumOpt) |
protected FSDataOutputStream |
FileSystem.primitiveCreate(Path f,

Validate the CreateFlag and throw exception if it is invalid
|
static void |
CreateFlag.validate(Object path,
boolean pathExists,
EnumSet<CreateFlag> flag)
Validate the CreateFlag for create operation
|
static void |
CreateFlag.validateForAppend(EnumSet<CreateFlag> flag)
