Package org.apache.hadoop.fs

Added Classes and Interfaces
Abortable	Abort data being written to a stream so that close() does not write the data.
BatchListingOperations	Interface filesystems MAY implement to offer a batched list.
ByteBufferPositionedReadable	Implementers of this interface provide a positioned read API that writes to a ByteBuffer rather than a {@code byte[]}.
FSBuilder	The base interface which various FileSystem FileContext Builder interfaces can extend and which underlying implementations will then implement.
FutureDataInputStreamBuilder	Builder for input streams and subclasses whose return value is actually a completable future: this allows for better asynchronous operation.
MultipartUploader	MultipartUploader is an interface for copying files multipart and across multiple nodes.
PartialListing	A partial listing of the children of a parent directory.

 

Changed Classes and Interfaces
AbstractFileSystem	This class provides an interface for implementors of a Hadoop file system (analogous to the VFS of Unix).
BlockLocation	Represents the network location of a block information about the hosts that contain block replicas and other block metadata (E.g.
ChecksumFileSystem	Abstract Checksumed FileSystem.
CommonConfigurationKeysPublic	This class contains constants for configuration keys used in the common code.
ContentSummary	Store the summary of a content (a directory or a file).
FSDataInputStream	Utility that wraps a FSInputStream in a DataInputStream and buffers input through a java.io.BufferedInputStream
FSDataOutputStream	Utility that wraps a OutputStream in a DataOutputStream
FSDataOutputStreamBuilder	Builder for FSDataOutputStream and its subclasses.
FSInputStream	FSInputStream is a generic old InputStream with a little bit of RAF-style seek ability.
FileContext	The FileContext class provides an interface for users of the Hadoop file system.
FileSystem	An abstract base class for a fairly generic filesystem.
FilterFileSystem	A FilterFileSystem contains some other file system which it uses as its basic file system possibly transforming the data along the way or providing additional functionality.
FsConstants	FileSystem related constants.
RawLocalFileSystem	Implement the FileSystem API for the raw local filesystem.
StreamCapabilities	Interface to query streams for supported capabilities.
