File stream connectors have been included with Kafka Connect distributions from the very beginning. These simple connectors were included to show case connector implementation but were never meant to be used in production and have been only available for the straightforward demonstration of Connect's capabilities through our quick start guides.
Given that these connectors are not production ready and yet they offer access to the local filesystem, with this ticket I propose to remove them from our deployments by default by excluding these connectors from the CLASSPATH or the default plugin.path.
The impact will be minimal. Quick start guides will require a single additional step of editing the plugin.path to include the single package that includes these connectors. Production deployments will remain unaffected because these are not production grade connectors.
