hadoop - AvroStorage with mapreduce and java.lang.RuntimeException: could not instantiate -

-

i have simple pig script, 

sensitiveset = load 'hdfs:///data/customerdata-20160128-1501807.avro' using org.apache.pig.piggybank.storage.avro.avrostorage(); dump sensitiveset;

when code executed in pig -x local mode runs smoothly, when executed in mapreduce mode got error below:
