Kafka - offset reset not working

DevOps Kafka
#1

Ok here is one weird issue that I am facing. I am trying to reset the topic for a consumer group. This is what I used.
./kafka-consumer-groups.sh --bootstrap-server 127.0.0.1:32400 --group group-tango --reset-offsets --to-earliest --topic topic-tango --execute
and the result that I got was.

group-tango  topic-tango      3           0
group-tango  topic-tango      0           0
group-tango  topic-tango      1           0
group-tango  topic-tango      5           0
group-tango  topic-tango      4           0
group-tango  topic-tango      2           0```
However, when I do
`./kafka-consumer-groups.sh --describe --bootstrap-server 127.0.0.1:32400 --group group-tango`
I am getting this.
```GROUP        TOPIC        PARTITION  CURRENT-OFFSET  LOG-END-OFFSET  LAG   CONSUMER-ID HOST CLIENT-ID
group-tango  topic-tango  1           2              5               3     -           -    - ```
As you see offset reset is not working. Is there anyway to fix this.

If you consumed two messages from partition 1, then looks correct to me

#3

But when I start consumer it is not consuming message from the beginning

#4

I even tried changing consumer group name but no luck

#5

--from-beginning (or auto.offset.reset) only applies if there is no committed offsets.

As shown, the committed offset for partition 1, for example, is not 0

#6

So how do I force consumer to start consuming message from the beginning

#7

I tried to reset offset bit it is not working. Basically all I want to consume message from that topic from the beginning.

#8

Your reset command is correct. But seems some consumer for that group is consuming again after you reset.

#9

Yeah thats true. I was under the impression that after reset consumer should be able to consumer message from the beginning.

#10

It will, but only for the very first run.

Note: Your consumer can always call seekToBeginning if you always want to consume from the start

Thank you very much for your help. I found out what the issue was.
