Package org.apache.hadoop.fs

Added Classes and Interfaces
BlockStoragePolicySpi	A storage policy specifies the placement of block replicas on specific storage types.
ByteBufferReadable	Implementers of this interface provide a read API that writes to a ByteBuffer not a byte[].
CanUnbuffer	FSDataInputStreams implement this interface to indicate that they can clear their buffers on request.
FSInputStream	FSInputStream is a generic old InputStream with a little bit of RAF-style seek ability.
GlobalStorageStatistics	Stores global storage statistics objects.
QuotaUsage	Store the quota usage of a directory.
StorageStatistics	StorageStatistics contains statistics data for a FileSystem or FileContext instance.

 

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.
CanSetDropBehind
CanSetReadahead
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
FileContext	The FileContext class provides an interface to the application writer for using the Hadoop file system.
FileStatus	Interface that represents the client side information for a file.
FileSystem	An abstract base class for a fairly generic filesystem.
FileUtil	A collection of file-processing util methods
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.
GlobFilter	A filter for POSIX glob pattern with brace expansions.
LocatedFileStatus	This class defines a FileStatus that includes a file's block locations.
Path	Names a file or directory in a FileSystem Path strings use slash as the directory separator.
PathFilter
PositionedReadable	Stream that permits positional reading.
RawLocalFileSystem	Implement the FileSystem API for the raw local filesystem.
Seekable	Stream that permits seeking.
Syncable	This interface for flush/sync operation.
Trash	Provides a trash facility which supports pluggable Trash policies.
TrashPolicy	This interface is used for implementing different Trash policies.
