## Uses of Class
org.apache.hadoop.fs.BlockLocation

Packages that use BlockLocation
org.apache.hadoop.fs | An abstract file system API.
org.apache.hadoop.fs.kfs | A client for the Kosmos filesystem (KFS)
org.apache.hadoop.mapred | A software framework for easily writing applications which process vast amounts of data (multi-terabyte data-sets) parallelly on large clusters (thousands of nodes) built of commodity hardware in a reliable, fault-tolerant manner.
org.apache.hadoop.mapreduce.lib.input |

Uses of BlockLocation in org.apache.hadoop.fs

Methods in org.apache.hadoop.fs that return BlockLocation
`BlockLocation[]` | `FilterFileSystem.getFileBlockLocations(FileStatus file, long start, long len)`
`BlockLocation[]` | `HarFileSystem.getFileBlockLocations(FileStatus file, long start, long len)` get block locations from the underlying fs
`BlockLocation[]` | `FileSystem.getFileBlockLocations(FileStatus file, long start, long len)` Return an array containing hostnames, offset and size of portions of the given file.

Uses of BlockLocation in org.apache.hadoop.fs.kfs

Methods in org.apache.hadoop.fs.kfs that return BlockLocation
`BlockLocation[]` | `KosmosFileSystem.getFileBlockLocations(FileStatus file, long start, long len)` Return null if the file doesn't exist; otherwise, get the locations of the various chunks of the file file from KFS.

Uses of BlockLocation in org.apache.hadoop.mapred

Methods in org.apache.hadoop.mapred with parameters of type BlockLocation
`protected int` | `FileInputFormat.getBlockIndex(BlockLocation[] blkLocations, long offset)`
`protected String[]` | `FileInputFormat.getSplitHosts(BlockLocation[] blkLocations, long offset, long splitSize, NetworkTopology clusterMap)` This function identifies and returns the hosts that contribute most for a given split.

Uses of BlockLocation in org.apache.hadoop.mapreduce.lib.input

Methods in org.apache.hadoop.mapreduce.lib.input with parameters of type BlockLocation
`protected int` | `FileInputFormat.getBlockIndex(BlockLocation[] blkLocations, long offset)`
