我正在用fargate在ecs上运行flink 1.7.2。我已经将我的作业的状态后端设置为rocksdb，路径=s3://。。。
在dockerfile中，我的基本图像是 1.7.2-hadoop27-scala_2.11 ，我运行以下两个命令：

RUN echo "fs.s3a.aws.credentials.provider: org.apache.flink.fs.s3hadoop.shaded.com.amazonaws.auth.ContainerCredentialsProvider" >> "$FLINK_CONF_DIR/flink-conf.yaml"
RUN cp /opt/flink/opt/flink-s3-fs-hadoop-1.7.2.jar /opt/flink/lib/flink-s3-fs-hadoop-1.7.2.jar

就像书上说的https://issues.apache.org/jira/browse/flink-8439
但是，我得到以下例外：

看着镜子 flink-s3-fs-hadoop-1.7.2.jar 我看到这个班的学生 ContainerCredentialsProvider 实际上是 org.apache.flink.fs.s3base.shaded.com.amazonaws.auth 我已经试过了：
添加 aws-sdk-core jar，并将凭据提供程序设置为 com.amazonaws.auth.ContainerCredentialsProvider （没有阴影）但是我得到了上面的问题链接中提到的问题
将凭据提供程序设置为 org.apache.flink.fs.s3base.shaded.com.amazonaws.auth.ContainerCredentialsProvider 但后来密码输入了 S3FileSystemFactory.java 在它前面加上 org.apache.flink.fs.s3hadoop.shaded. 有什么办法可以找到这个班吗？
