Subject [jira] [Commented] (KAFKA-4327) Move Reset Tool from core to streams
Date Wed, 26 Jul 2017 13:23:00 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-4327?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16101659#comment-16101659

Matthias J. Sax commented on KAFKA-4327:

It's Streams tool, so it belongs to package `o.a.k.streams.tools` -- we only put it into core
because of the ZK dependency and we did not want to add ZK dependency to streams module. \cc

> Move Reset Tool from core to streams
> ------------------------------------
>                 Key: KAFKA-4327
>                 URL: https://issues.apache.org/jira/browse/KAFKA-4327
>             Project: Kafka
>          Issue Type: Improvement
>          Components: streams
>            Reporter: Matthias J. Sax
>            Assignee: Jorge Quilcate
>            Priority: Minor
> This is a follow up on https://issues.apache.org/jira/browse/KAFKA-4008
> Currently, Kafka Streams Application Reset Tool is part of {{core}} module due to ZK
dependency. After KIP-4 got merged, this dependency can be dropped and the Reset Tool can
be moved to {{streams}} module.
> This should also update {{InternalTopicManager#filterExistingTopics}} that revers to
ResetTool in an exception message:
> {{"Use 'kafka.tools.StreamsResetter' tool"}}
> -> {{"Use '" + kafka.tools.StreamsResetter.getClass().getName() + "' tool"}}
> Doing this JIRA also requires to update the docs with regard to broker backward compatibility
-- not all broker support "topic delete request" and thus, the reset tool will not be backward
compatible to all broker versions.
