Methods in org.apache.hadoop.fs that return BlockLocation

Modifier and Type	Method and Description
BlockLocation[]	LocatedFileStatus.getBlockLocations() Get the file's block locations
BlockLocation[]	FileSystem.getFileBlockLocations(FileStatus file, long start, long len) Return an array containing hostnames, offset and size of portions of the given file.
BlockLocation[]	FilterFileSystem.getFileBlockLocations(FileStatus file, long start, long len)
BlockLocation[]	FileSystem.getFileBlockLocations(Path p, long start, long len) Return an array containing hostnames, offset and size of portions of the given file.
abstract BlockLocation[]	AbstractFileSystem.getFileBlockLocations(Path f, long start, long len) The specification of this method matches that of FileContext.getFileBlockLocations(Path, long, long) except that Path f must be for this file system.
BlockLocation[]	FileContext.getFileBlockLocations(Path f, long start, long len) Return blockLocation of the given file for the given offset and len.
