BlockLocation[] |
LocatedFileStatus.getBlockLocations()
Get the file's block locations
In HDFS, the returned BlockLocation will have different formats for
replicated and erasure coded file.
|
BlockLocation[] |
FilterFileSystem.getFileBlockLocations(FileStatus file,
long start,
long len) |
BlockLocation[] |
FileSystem.getFileBlockLocations(FileStatus file,
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[] |
FileSystem.getFileBlockLocations(Path p,
long start,
long len)
Return an array containing hostnames, offset and size of
portions of the given file.
