我正在尝试通过java运行pig脚本。下面是我的代码现在的样子：

public static void main(String[] args) throws JSONException, InterruptedException, IOException {    
    Properties props = new Properties();
    props.setProperty("fs.default.name", "hdfs://<some-value>:8020");
    props.setProperty("mapred.job.tracker", "<some-value>:54311");
    PigServer pigServer = new PigServer(ExecType.MAPREDUCE, props);

    Map<String, String> params = new LinkedHashMap<String, String>();
    params.put("INPUT_PATH", "hdfs://<some-input-value>");
    params.put("OUTPUT_FILE", "hdfs:///user/<some-username>/last-login-out");

    pigServer.registerScript("last-login-by-userid.pig", params);
}

但每当我运行程序时，我会得到：

Exception in thread "main" org.apache.pig.backend.executionengine.ExecException: ERROR 4010: Cannot find hadoop configurations in classpath (neither hadoop-site.xml nor core-site.xml was found in the classpath). If you plan to use local mode, please put -x local option in command line.

我已经把房子搬走了 pig-0.10.1 我从apache网站下载到的文件夹 Applications 并添加了 export PIG_HOME=/Applications/pig-0.10.1 在我的 ~/.bash_profile .
当我登录到 <some-value>:8020 服务器，我可以运行Pig脚本很好。
