Я пытаюсь настроить S3 как бэкэнд моего состояния с Flink 1.6.0.
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
Я переместил flink-s3-fs-hadoop-1.6.0.jar в каталог lib.В документах не указывается необходимость в файлах конфигурации hadoop для этого конкретного метода.Тем не менее, я сталкиваюсь с этой ошибкой, жалуясь на отсутствие пути конфигурации hadoop.
