[jira] [Commented] (KAFKA-4793) Kafka Connect: POST /connectors/(string: name)/restart doesn't start failed tasks

["Randall Hauch (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-4793?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17355287#comment-17355287 ] 

Randall Hauch commented on KAFKA-4793:
--------------------------------------

I'm picking this up, and will add a KIP that proposes adding query parameters to the existing `/connectors/{name}/restart` API. One query parameter will specify whether to also include tasks when determining the instances to restart, and another query parameter that will specify whether to restart only failed instances.

I will post the link to the KIP here as soon as I've created it.

> 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.
