Release Note:

Hide
By default, if there is an official filesystem plugin for a given schema, it will not be allowed to use fallback filesystem factories (like HADOOP libraries on the classpath) to load it. Added {{fs.allowed-fallback-filesystems}} configuration option to override this behaviour.

Description

Currently, if no s3 plugin is included, hadoop is used as a fallback, which introduces a wide variety of problems. We should probably only white list specific protocols that work well (e.g. hdfs).
