The issue is that Streaming expects the old/stable MR API (org.apache.hadoop.mapred.InputFormat) as its input format class, but your WholeFileInputFormat is using the new MR API (org.apache.hadoop.mapreduce.lib.input.InputFormat). Using the older form will let you pass.
This has nothing to do with your version/distribution of Hadoop.
