我正试图用flink1.6.0将s3配置为我的状态后端。

flink-conf.yaml
state.backend: filesystem
state.checkpoints.dir: s3://***/flink-checkpoints
state.savepoints.dir: s3://***/flink-savepoints

s3.access-key:*******
s3.secret-key:*******

https://ci.apache.org/projects/flink/flink-docs-stable/ops/deployment/aws.html#shaded-hadooppresto-s3-file-systems-推荐
我已经将flink-s3-fs-hadoop-1.6.0.jar移到lib目录。这些文档没有为这个特定方法指定任何hadoop配置文件的需要。但是我正面临这个错误，抱怨缺少hadoop配置路径。

我是不是漏了什么？感谢您的帮助。
