Regular S3 files would not have the type metadata so S3FileSystem would not try to interpret them as inodes. > An extension to write regular files to S3 would not be covered by this change - we could do this as a separate piece of work (we still need to decide whether to introduce another scheme - e.g. rename block-based S3 to "s3fs" and call regular S3 "s3" - or whether to just use a configuration property to control block-based vs. regular writes). -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
