Tejas Patil updated KAFKA-559:
------------------------------
Attachment: KAFKA-559.v1.patch
Attached KAFKA-559.v1.patch above.
- It has been developed to work do cleanup with "group-id" as input from user
instead of "topic".
- An additional "dry-run" feature is provided so that people can see what all
znodes would get deleted w/o actually deleting them.
> Garbage collect old consumer metadata entries

> Many use cases involve tranient consumers. These consumers create entries
> under their consumer group in zk and maintain offsets there as well. There is
> currently no way to delete these entries. It would be good to have a tool
> that did something like
> bin/delete-obsolete-consumer-groups.sh [--topic t1] --since [date]
> --zookeeper [zk_connect]
> This would scan through consumer group entries and delete any that had no
> offset update since the given date.
