            Description

            Transferred from MAPREDUCE-2194:

            We have upgraded our dev environment from Cloudera's 0.20.2-228-cloudera to 0.20.2-737-cloudera

            Version 228 worked great for us. In version 737 we are getting the following exception:

            (LocalJobRunner.java:295) - job_local_0005
            java.lang.ClassCastException: org.apache.hadoop.mapreduce.lib.input.FileSplit cannot be cast to org.apache.hadoop.mapred.InputSplit
            at org.apache.hadoop.mapred.MapTask.runOldMapper(MapTask.java:357)
            at org.apache.hadoop.mapred.MapTask.run(MapTask.java:317)
            at org.apache.hadoop.mapred.LocalJobRunner$Job.run(LocalJobRunner.java:212)

            We have tried to set job.getConfiguration().setBoolean("mapred.reducer.new-api", true) but that did not resolve the issue.
