我在试着写一个Pig的剧本

register 'hdfs://localhost:8020/user/pig/jars/postgresql-9.3-1100.jdbc4.jar';
register 'hdfs://localhost:8020/user/pig/jars/piggybank.jar';
a = load 'hdfs://localhost:8020/user/hive/warehouse/outage' USING PigStorage(',') AS (no:int, name:chararray, age:int);
STORE a INTO 'test' USING org.apache.pig.piggybank.storage.DBStorage('org.postgresql.Driver','jdbc:postgresql://127.0.0.1:5432/hivedata','postgres','123','INSERT INTO test (no, name, age)values(?,?,?)');

我正在从hive获取数据，但无法写入postgresql

ERROR org.apache.pig.backend.hadoop.executionengine.mapReduceLayer.Launcher - Backend     error message
java.io.IOException: java.lang.RuntimeException: JDBC error
