    Description

      Instead the generic error message:

      Backend error message
      ---------------------

      Caused by: org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.partitioners.MalFormedProbVecException: ERROR 2122: Sum of probabilities should be one
      at org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.partitioners.DiscreteProbabilitySampleGenerator.<init>(DiscreteProbabilitySampleGenerator.java:56)
      at org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.partitioners.WeightedRangePartitioner.setConf(WeightedRangePartitioner.java:128)
      ... 10 more

      it can easily print out the content of the malformed probability vector.
