Vahid Hashemian updated KAFKA-3129:
-----------------------------------
Attachment: kafka-3129.mov
The observed behavior is different between when the producer is run in the
console and when it is run via the IDE (eclipse).
>From console and with 10,000 messages, as described so far, about 50% of the
>times the consumer stops at 9,864 rather than going all the way to 10,000.
>When producer is run within the IDE, most of the times, the consumer goes up
>to 9,864, then pauses for a fraction of a second, and then it continues to
>consume the rest of the message, as shown in this video.
> Potential Console Producer/Consumer Issue

>
> 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.
> I also ran the same experiment with a similar file of 10,000 lines, and am
> getting a similar behavior. When the consumer does not receive all the 10,000
> messages it usually stops at 9,864.
