Thanks yall, Yangze, > I've tried to use MinIO as state backend and everything seems works well For clarity, I'm using RocksDB state backend with Minio as state storage. > s3.endpoint: http://localhost:9000 Also, I'm doing everything from docker-compose so localhost isn't going to work in my case.
Arvid, > You definitely need to use an http endpoint. I always receive errors like the following when I use http: Caused by: java.util.concurrent.CompletionException: org.apache.flink.core.fs.UnsupportedFileSystemSchemeException: Could not find a file system implementation for scheme 'http'. The scheme is not directly supported by Flink and no Hadoop file system to support this scheme could be loaded. For a full list of supported file systems, please see https://ci.apache.org/projects/flink/flink-docs-stable/ops/filesystems/. Whereas s3:// gives me Bad Request errors instead Thanks On Wed, Sep 9, 2020 at 8:03 AM Arvid Heise <ar...@ververica.com> wrote: > Hi Rex, > > you could also check the end to end tests that use minio in flink's repo. > You definitely need to use an http endpoint. > > The setup [1] uses also another way to specify the s3.path.style.access > (with dashes).
