    Default Error on Pentaho Map Reduce Step connecting to Cloudera

    I am getting the following error trying to execute a job that invokes Pentaho MapReduce step; it seems that the property mapreduce.job.name has not been set by the step and must be included manually in a configuration file. I am using PDI 6 and a CDH 5.4 VM on a single node.
