Hadoop S3列表存储桶内容错误

Question

不确定我在这里缺少什么。解决使用hadoop 2.7.1从s3尝试存储桶内容时得到的以下消息的最佳方法是什么？这应该是非常直接的，我有我的core-site.xml和hdfs-site.xml文件，如下所示，然后我尝试运行hadoop fs -ls s3a://<bucket_name>

HDFS-site.xml中：

<configuration>
  <property>
    <name>fs.s3a.access.key</name>
    <value>key</value>
  </property>
  <property>
    <name>fs.s3a.secret.key</name>
    <value>secret</value>
  </property>
</configuration>

核心-site.xml中：

<configuration>
    <property>
        <name>fs.s3a.impl</name>
        <value>org.apache.hadoop.fs.s3a.S3AFileSystem</value>
    </property>
</configuration>

错误讯息：
