Vahid Hashemian commented on KAFKA-3129: ---------------------------------------- [~pmishra01] I tried this on Ubuntu, Windows 7 and Windows 10 but were not able to reproduce it after a few tries. Please note that the default {{acks}} value has changed from 0 to 1 based on the [this PR|https://github.com/apache/kafka/pull/1795]. So if you like to try producing with {{acks=0}} you'd have to overwrite the default. > Console producer issue when request-required-acks=0 > --------------------------------------------------- > > Key: KAFKA-3129 > URL: https://issues.apache.org/jira/browse/KAFKA-3129 > Project: Kafka > Issue Type: Bug > Components: producer > Affects Versions: 0.9.0.0, 0.10.0.0 > Reporter: Vahid Hashemian > Assignee: Dustin Cote > Attachments: kafka-3129.mov, server.log.abnormal.txt, > server.log.normal.txt > > > 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
