Subject Re: how to modify offsets stored in Kafka in version?
Date Fri, 19 Jun 2015 13:43:50 GMT
Thanks, Stevo, for the quick reply,
Yes, I understand how to do this programmatically - but I would like to be able to do this
manually from a command line, just as before I was able to do this in the Zookeeper shell.
I don't want to write and run a Java app just to set an offset :)

[unless, of course, this is the only way to do this.....]

Hello Marina,

There's Kafka API to fetch and commit offsets
- maybe it will work for you.

Kind regards,
Stevo Slavic.
