>  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.
