我正在尝试从eclipse中执行apachepig代码，如中所述http://pig.apache.org/docs/r0.12.0/test.html
以下是代码：
pom.xml文件

pigunit测试用例：

import java.io.IOException;

import org.apache.pig.pigunit.PigTest;
import org.apache.pig.tools.parameters.ParseException;
import org.junit.Test;

public class PigUnitTestPractise {
      @Test
      public void testTop2Queries() throws IOException, ParseException {
        String[] args = {
            "n=2",
            };

        PigTest test = new PigTest("resources/top_queries.pig", args);

        String[] input = {
            "yahoo",
            "yahoo",
            "yahoo",
            "twitter",
            "facebook",
            "facebook",
            "linkedin",
        };

        String[] output = {
            "(yahoo,3)",
            "(facebook,2)",
        };

        test.assertOutput("data", input, "queries_limit", output);
      }

}

错误：

根据post java.lang.verifyerror，我可能在导入顺序上有问题。
根据how to fix java.lang.verifyerror？，我可能是在“针对不同版本的库运行代码，而不是针对不同版本的库编译代码”。
如何找到问题的确切根源？哪个jar会产生问题？

JavahadoopMaveneclipseapache-pig

找不到根本原因，但是使用不同的依赖项解决了错误。我在maven依赖中使用了cdh4.5存储库jar来解决这个问题。
仅更改pom.xml:

</project>

附笔
这是否是pig和hadoopapi之间的不兼容（即pig0.12与hadoop2.2.0不兼容）？
