我有一个用java嵌入pig的程序。我在本地模式下执行pig服务器。但是当我执行我的代码时，我有一个执行错误。我不知道¡我不知道这意味着这个错误。
java代码是：

try {
        System.out.println("principio de carga estadisticas");
        Properties props = new Properties();
        props.setProperty("fs.default.name","hdfs://localhost.localdomain:8020");
        //System.out.println("cargar estadisticas paso1");
        props.setProperty("mapred.job.tracker","localhost.localdomain:8021");
        System.out.println("cargar estadisticas paso 11 jjjj");
        PigServer pigServer = new PigServer("local");

错误的句子是

PigServer pigServer = new PigServer("local");

例外情况是：

principio de carga estadisticas
cargar estadisticas paso 11 jjjj

我拿错jar了吗？。如何配置hdfs或pig？
