             Summary: Potential Console Producer/Consumer Issue
                 Key: KAFKA-3129
                 URL: https://issues.apache.org/jira/browse/KAFKA-3129
             Project: Kafka
          Issue Type: Bug
          Components: consumer, producer 
    Affects Versions: 0.9.0.0
            Reporter: Vahid Hashemian
            Assignee: Neha Narkhede


I have been running a simple test case in which I have a text file {{messages.txt}} with 1,000,000 lines (lines contain numbers from 1 to 1,000,000 in ascending order). I run the console consumer like this:

{{$ bin/kafka-console-consumer.sh --zookeeper localhost:2181 --topic test}}

Topic {{test}} is on 1 partition with a replication factor of 1.

Then I run the console producer like this:

{{$ bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test < messages.txt}}

Then the console starts receiving the messages. And about half the times it goes all the way to 1,000,000. But, in other cases, it stops short, usually at 999,735.

I tried running another console consumer on another machine and both consumers behave the same way. I can't see anything related to this in the logs.
