> In order to use any given non-AWS s3 implementation backed by the presto s3 filesystem, it is necessary to set at least one configuration parameter in flink-conf.yaml:
> * presto.s3.endpoint: https://example.com
> This appears to work as expected for hosted s3 alternatives.
> In order to use a bring-your-own, self-hosted s3 alternative like [minio|https://www.minio.io/], at least two configuration parameters are required:
> * presto.s3.endpoint: https://example.com
> * presto.s3.path-style-access: true
> However, the second path-style-access parameter doesn't work because the 0.185 version of presto doesn't support passing through that configuration option to the hive s3 client.
> To work around the issue, path-style-access can be forced on the s3 client by using an IP address for the endpoint (instead of a hostname). Without this workaround, flink attempts to use the virtualhost-style at bucketname.example.com, which fails unless the expected DNS records exist.
> To solve this problem and enable non-IP endpoints, upgrade the [pom|https://github.com/apache/flink/blob/master/flink-filesystems/flink-s3-fs-presto/pom.xml#L36] to at least 0.186 which includes [this commit|https://github.com/prestodb/presto/commit/0707f2f21a96d2fd30953fb3fa9a9a03f03d88bd] Note that 0.213 is the latest presto release.
