Package org.apache.hadoop.tools.dynamometer.blockgenerator

Class BlockInfo

java.lang.Object

org.apache.hadoop.tools.dynamometer.blockgenerator.BlockInfo

All Implemented Interfaces:

org.apache.hadoop.io.Writable

public class BlockInfo
extends java.lang.Object
implements org.apache.hadoop.io.Writable

This is the MapOutputValue class. It has the blockId and the block generation stamp which is needed to generate the block images in the reducer. This also stores the replication of the block, but note that it does not serialize this value as part of its Writable interface, and does not consider the replication when doing equality / hash comparisons.
