101
102

猪脚本:

REGISTER required jars are registered;

A = LOAD 'test.csv'  USING org.apache.pig.piggybank.storage.CSVExcelStorage() AS (code:chararray);

STORE A INTO 'test' USING org.apache.pig.piggybank.storage.avro.AvroStorage
    ('schema',
    '{"namespace":"com.pig.test.avro","type":"record","name":"Avro_Test","doc":"Avro Test Schema",
        "fields":[
            {"name":"code","type":["string","null"],"default":null}
            ]}'
    );

存储时出现运行时错误。关于解决相同问题的任何输入。
