Subject [jira] [Commented] (KAFKA-6221) ReplicaFetcherThread throws UnknownTopicOrPartitionException on topic creation
Date Fri, 17 Nov 2017 09:20:00 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-6221?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16256703#comment-16256703
] 

Alex Dunayevsky commented on KAFKA-6221:
----------------------------------------

*huxihx*, thank you for the explanation! Nope, no exceptions later, everything works fine,
but it's quite confusing to observe this when deploying Kafka in production... I believe this
should not be considered as a normal Kafka behavior and should be fixed. What do you think?

>                 URL: https://issues.apache.org/jira/browse/KAFKA-6221
>             Project: Kafka
>          Issue Type: Bug
>          Components: core
>    Affects Versions: 0.10.2.0, 0.10.2.1
>         Environment: RHEL 7
>            Reporter: Alex Dunayevsky
>   Original Estimate: 336h
>  Remaining Estimate: 336h
>
> This issue appeared to happen frequently on 0.10.2.0. 
> On 0.10.2.1 it's a way harder to reproduce. 
> We'll focus on reproducing it on 0.10.2.1.
> *TOPOLOGY:* 
>   3 brokers, 1 zk.
> *REPRODUCING STRATEGY:* 
> Create a few dozens topics (say, 40) one by one, each with replication factor 2. Number
of partitions, generally, does not matter but, for easier reproduction, should not be too
small (around 30 or so). 
> *CREATE 40 TOPICS:*
> {code:java} for i in {1..40}; do bin/kafka-topics.sh --create --topic "topic${i}_p28_r2"
--partitions 28 --replication-factor 2 --zookeeper :2165; done {code}

> {code}
> *RESULTS:*
> As you can see, the problem occurs on 
> * partitions [3,9,15,21,27] of topic `{{topic1_p28_r2}}`
> * partitions [0,6,12,18,14] of topic `{{topic20_p28_r2}}`
> * partitions [4,10,16,22]    of topic `{{topic30_p28_r2}}`
> Partitions are either odd or even.
> Every "unlucky" partition, except the starting one, for each topic, appears to be the
6th in the row. For instance: 
> * 3, 9(3+6), 15(3+6+6), ...
> * 0, 6(0+6), 12(0+6+6), ...
> * 4, ...
