大家好，
我正在使用S3文件源在AWS EMR上运行Flink，但出现以下错误：“ org.apache.flink.fs.s3hadoop.shaded.com.amazonaws.SdkClientException：无法清理XML发往处理程序类的文档... “
似乎有太多文件要读取（超过10万个文件）时，就会出现此错误
根据https://ci.apache.org/projects/flink/flink-docs-stable/ops/deployment/aws.html页，在EMR上运行时，无需对S3文件进行任何配置。
完整的堆栈跟踪信息粘贴在下面。 我认为此错误是在EMR / AWS SDK方面，而不是Flink。 有人可以帮忙吗？
感谢和问候， 阿韦雷尔
