I am using Kafka 0.8.1 with kafka-python tool and I have noticed that the consumer group has no effect on the offset. The consumer keeps reading all the messages form the beginning and when I launch two instances of the same python script the consumers get the same messages, from the beginning to

I found a portion on the code to uncoment when using 0.8.1 but that causes and error when the library is called

"...
consumer = SimpleConsumer(kafka, "my-group", topic, auto_commit=False)
File "build/bdist.linux-x86_64/egg/kafka/consumer.py", line 242, in init
File "build/bdist.linux-x86_64/egg/kafka/consumer.py", line 111, in init
NameError: global name 'OffsetFetchRequest' is not defined
..."

This is the python script:

localconsumer.py

from kafka.client import KafkaClient
from kafka.consumer import SimpleConsumer
from kafka.producer import SimpleProducer, KeyedProducer

kafka = KafkaClient("localhost:9092")
topic = "test"

To consume messages

consumer = SimpleConsumer(kafka, "my-group", topic, auto_commit=False)
for message in consumer:
print message

kafka.close()
