HADDOP fileOutputformat.setOutputPath问题

Question

我在为Hadoop工作设置输出格式时遇到了问题。

使用Amazon EMR运行代码时，我会将其转到STDERR：

Exception in thread "main" java.lang.IllegalAccessError: class org.apache.hadoop.hdfs.web.HftpFileSystem cannot access its superinterface org.apache.hadoop.hdfs.web.TokenAspect$TokenManagementDelegator

while main.main（main.java：68）是：

Job firstMapReduceJob = Job.getInstance(conf1, "firstMapReduce");
.
.
.
FileOutputFormat.setOutputPath(firstMapReduceJob, new Path("s3n://bucket-name/test"));
firstMapReduceJob.setOutputFormatClass(TextOutputFormat.class);

我的存储桶存在，我有一个名为“ test”的文件夹。 我可以在Amazon EMR上看到我的群集，因此我拥有所有设置的AWS证书。 将很高兴提供更多需要的代码。

编辑：Hadoop版本为2.7.2：

        <dependency>
            <groupId>org.apache.hadoop</groupId>
            <artifactId>hadoop-common</artifactId>

预先感谢。
