[Yanwen Lin]

Hi Kafka team,

Can I ask for a contributor permission so that I can assign myself to the Kafka 
Jira ticket. My Jira id is: ll1124278064

Thanks!

Best,

Failed Unit testings in ReassignPartitionsIntegrationTest

[Yanwen Lin]

Hi folks,

I just joined Kafka community. I would like to work on a beginner issue but get 
blocked on running unit testings:
I found that I have issue with running the following two unit testings even w/ 
a fresh git clone of the Kafka repo on trunk branch:
ReassignPartitionsIntegrationTest. testReassignment() => I never passed this 
test
ReassignPartitionsIntegrationTest. testReassignmentWithAlterIsrDisabled() ==> 
This is a flaky test, sometimes I can pass but sometimes not.
I ran the following Gradle command:

$./gradlew core:test --tests ReassignPartitionsIntegrationTest

My Java version is:
$ java -version
java version "1.8.0_172-ea"
Java(TM) SE Runtime Environment (build 1.8.0_172-ea-b03)
Java HotSpot(TM) 64-Bit Server VM (build 25.172-b03, mixed mode)

My Scala version is:
$ scala -version
Scala code runner version 2.13.1 -- Copyright 2002-2019, LAMP/EPFL and 
Lightbend, Inc.

I did a search in the Jira tickets and there is only one I found related to 
this issue: https://issues.apache.org/jira/browse/KAFKA-12933 
.

Does anyone encounter this issue before? Thanks!

Best,
Yanwen

Re: Failed Unit testings in ReassignPartitionsIntegrationTest

Hi Luke,

Thanks for your suggestion! I will try to test in in VM/Docker. 

BTW, may I know the exact java/scala version used in your local env (e.g. 
jdk1.8.0_172 / Scala 2.13.1)? Just would like to rule out this factor.

Best,
Yanwen

Review Request for KAFKA-13032

[Yanwen Lin]

Hi folks,

May I ask a review request for this PR: 
https://github.com/apache/kafka/pull/11241 
? It’s a quite simple beginner 
issue.

Just joined our community so not sure if I missed any convention about asking 
PR review. Plz let me know if this is not polite. Thanks!

Best
Yanwen
