[jira] [Updated] (KAFKA-467) Controller based leader election
failed ERROR messages in LazyInitProducerTest
[ https://issues.apache.org/jira/browse/KAFKA-467?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yang Ye updated KAFKA-467:
--------------------------
Attachment: kafka_467.diff
Neha,
This exception:
[info] Test Starting: testMultiProduce(kafka.integration.LazyInitProducerTest)
[2012-08-17 08:46:45,165] ERROR Timing out after 500 ms since leader is not elected for topic test1 partition 0 (kafka.utils.TestUtils$:93)
is due to the line of code TestUtils.waitUntilLeaderIsElectedOrChanged()....
But this line of code is not needed here, because the topics are not created initially, they're created on the fly when the server receives produce requests to these topics. So they will definitely hit the timeout exception.
I've checked out svn version 1367821, which is before the controller code is checked in, the same exceptions are there.
The way to fix it is just to remove the waitUntil() lines.
