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)
