Randall Hauch commented on KAFKA-4793:
--------------------------------------
I've created a KIP that expands the existing REST API method to restart a
connector (the `Connector` instance, not the "named connector") with two new
optional query parameters. Users can make one call using this method (with the
query parameters) to request a combination of failed/all `Connector` and/or
`Task` instances.

> Kafka Connect: POST /connectors/(string: name)/restart doesn't start failed

> Sometimes tasks stop due to repeated failures. Users will want to restart the
> connector and have it retry after fixing an issue.
> We expected "POST /connectors/(string: name)/restart" to cause retry of
> failed tasks, but this doesn't appear to be the case.
