我在hadoop（cdh5.5.1）上运行aws kinesis时遇到了一个奇怪的错误。
我可以用这个简单的类重现错误：

import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.services.kinesis.AmazonKinesisClient;
import org.apache.hadoop.conf.Configured;
import org.apache.hadoop.util.Tool;
import org.apache.hadoop.util.ToolRunner;
import org.joda.time.format.DateTimeFormat;

public class CollectJob extends Configured implements Tool {

    public static void main(String[] args) throws Exception {

        int exitCode = ToolRunner.run(new CollectJob(), args);
        System.exit(exitCode);
    }

    @Override
    public int run(String[] args) throws Exception {

        System.out.println(DateTimeFormat.class);
        System.out.println(DateTimeFormat.class.getProtectionDomain().getCodeSource().getLocation());

        System.out.println(AmazonKinesisClient.class);
        System.out.println(AmazonKinesisClient.class.getProtectionDomain().getCodeSource().getLocation());

        AWSCredentials credentials = new BasicAWSCredentials("toto", "tata");
        AmazonKinesisClient kinesisClient = new AmazonKinesisClient(credentials);
        kinesisClient.setEndpoint("kinesis.eu-west-1.amazonaws.com");

        return 0;
    }
}

然后我运行main：

yarn jar event-collector-1.0-SNAPSHOT.jar CollectJob

得到这个标准：

我尝试了yarn\u user\u classpath\u first true或false，得到了相同的错误。我不明白怎么了。。。
救命！：）
编辑更多细节：也失败：

@Override
    public int run(String[] args) throws Exception {

        //print DateTimeFormat class infos
        System.out.println(DateTimeFormat.class);
        System.out.println(DateTimeFormat.class.getProtectionDomain().getCodeSource().getLocation());

        //print AWS4Signer class infos
        System.out.println(AWS4Signer.class);
        System.out.println(AWS4Signer.class.getProtectionDomain().getCodeSource().getLocation());

        //test joda time class (copy-paste from AWS4Signer source code)
        DateTimeFormatter dateFormatter = DateTimeFormat.forPattern("yyyyMMdd").withZoneUTC();
        System.out.println(dateFormatter);

        //create AWS4Signer instance -> ClassNotFound on DateTimeFormat !!!
        AWS4Signer signer = new AWS4Signer();
        System.out.println(signer);

        return 0;
    }
