    java.lang.IllegalArgumentException: checkLocalJobRunnerConfiguration: When using LocalJobRunner, you cannot run in split master / worker mode since there is only 1 task at a time!" I fixed this by adding an entry in mapred-site.xml for mapreduce.jobtracker.address but now i am getting a different error: *Exception in thread "main" java.lang.IncompatibleClassChangeError: Found interface org.apache.hadoop.mapreduce.JobContext, but class was expected*
