Flink Shaded Hadoop S3文件系统仍然需要hdfs-default和hdfs-site配置路径

我正在尝试使用Flink 1.6.0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-recommended

我已将flink-s3-fs-hadoop-1.6.0.jar移动到lib目录中。文档没有为此特定方法指定任何hadoop配置文件的需要。然而，我正面临这个错误抱怨缺少hadoop配置路径。

我有没有错过什么？
