| <div class="block">Return an array containing hostnames, offset and size of |
| portions of the given file. For nonexistent |
| file or regions, <code>null</code> is returned. |
| |
| <pre> |
| if f == null : |

| elif f.getLen() <= start: |
| result = [] |
| else result = [ locations(FS, b) for b in blocks(FS, p, s, s+l)] |
| </pre> |
| This call is most helpful with and distributed filesystem |
| where the hostnames of machines that contain blocks of the given file |
| can be determined. |
| |
| The default implementation returns an array containing one element: |
| <pre> |
| BlockLocation( { "localhost:9866" }, { "localhost" }, 0, file.getLen()) |
| </pre> |
| |
| In HDFS, if file is three-replicated, the returned array contains |
| elements like: |
| <pre> |
| BlockLocation(offset: 0, length: BLOCK_SIZE, |
| hosts: {"host1:9866", "host2:9866, host3:9866"}) |
| BlockLocation(offset: BLOCK_SIZE, length: BLOCK_SIZE, |
| hosts: {"host2:9866", "host3:9866, host4:9866"}) |
| </pre> |
| |
| And if a file is erasure-coded, the returned BlockLocation are logical |
| block groups. |
| |
| Suppose we have a RS_3_2 coded file (3 data units and 2 parity units). |
| 1. If the file size is less than one stripe size, say 2 * CELL_SIZE, then |
| there will be one BlockLocation returned, with 0 offset, actual file size |
| and 4 hosts (2 data blocks and 2 parity blocks) hosting the actual blocks. |
| 3. If the file size is less than one group size but greater than one |
| stripe size, then there will be one BlockLocation returned, with 0 offset, |
| actual file size with 5 hosts (3 data blocks and 2 parity blocks) hosting |
| the actual blocks. |
| 4. If the file size is greater than one group size, 3 * BLOCK_SIZE + 123 |
| for example, then the result will be like: |
| <pre> |
| BlockLocation(offset: 0, length: 3 * BLOCK_SIZE, hosts: {"host1:9866", |
| "host2:9866","host3:9866","host4:9866","host5:9866"}) |
