Yan Fang commented on SAMZA-185:
--------------------------------
It happends all the time. I compared the two logs (one is working version and
another one is not-working version).
Not-working one:
{code}

The not-working one missed this line:

14:43:30.828 [DEBUG] [TestEventLogger] 5789 [SAMZA-BROKER-PROXY] INFO

Is this the reason?
> Upgrade Samza to Kafka 0.8.1
> ----------------------------
>
> Key: SAMZA-185
> URL: https://issues.apache.org/jira/browse/SAMZA-185
> Project: Samza
> Issue Type: Bug
> Components: build
> Affects Versions: 0.7.0
> Reporter: Chris Riccomini
> Labels: easyfix
> Attachments: SAMZA-185.1.patch, SAMZA-185.patch
>
>
> We should upgrade Kafka to 0.8.1. This involves:
> 1. Switch to using Kafka's maven dependencies
> (http://repo.maven.apache.org/maven2/org/apache//kafka/kafka_2.10/0.8.1/)
> instead of checking in JARs.
> 2. Upgrade build.gradle and gradle dependency versions to depend on 0.8.1.
> 3. Update index.md in docs to no longer say "It depends on a snapshot version
> of Kafka that will not officially be released for a few months."
