Key: MAPREDUCE-4251
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4251
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv1
Affects Versions: 0.22.0
Reporter: Benoy Antony

Priority: Minor
Fix For: 0.22.1
org.apache.hadoop.mapred.lib.InputSampler#Sampler in Hadoop 0.20 has been
moved to org.apache.hadoop.mapreduce.lib.partition.InputSampler#Sampler in
Hadoop 0.22
The arguments of the getSample method in the Sampler class have also been
changed, 0.22 use the new InputFormat, and 0.20 use the deprecated InputFormat,
0.22 use org.apache.hadoop.mapreduce.Job and 0.20use
org.apache.hadoop.mapred.JobConf.
So the programs compiled with old api has to be changed.
