Kafka 0.11.0.0 (Confluent 3.3.0) added support to manipulate offsets for a consumer group via cli kafka-consumer-groups command.

1. List the topics to which the group is subscribed

kafka-consumer-groups --bootstrap-server <kafkahost:port> --group <group_id> --describe

Note the values under "CURRENT-OFFSET" and "LOG-END-OFFSET". "CURRENT-OFFSET" is the offset where this consumer group is currently at in each of the partitions.

2. Reset the consumer offset for a topic (preview)

; A REPL-based, annotated Seesaw tutorial
; Please visit https://github.com/daveray/seesaw for more info
;
; This is a very basic intro to Seesaw, a Clojure UI toolkit. It covers
; Seesaw's basic features and philosophy, but only scratches the surface
; of what's available. It only assumes knowledge of Clojure. No Swing or
; Java experience is needed.
;
; This material was first presented in a talk at @CraftsmanGuild in
; Ann Arbor, MI.

<pil> Quel dommage pour La Peste et d'autres Mathématiciens de la Musique
<pil> Il suffirait pourtant qu'ils se laissent aller à écouter de la musique électronique pas seulement en rave pour apprécier cette performance.. 
<pil> Ces pauvres gens n'ont jamais du écouter du Praxis, Reverse, Explore Toi, Cavage, Planet Mu , Schematic, Warp etc.
