Thanks. I'm looking at the s3 example and I can only find the S3FileSystemFactory but not the File System implementation (subclass of org.apache.flink.core.fs.FileSystem). Is that requirement still needed? On Wednesday, January 17, 2018, 3:59:47 PM PST, Fabian Hueske <fhue...@gmail.com> wrote: Hi,
please have a look at this doc page [1]. It describes how to add new file system implementations and also how to configure them.
