Yang Ye updated KAFKA-344:
--------------------------
Attachment: kafka_344_draft.patch
Sorry the system test is still not done yet. The current system test framework
assume a global "cluster_config.json" file, it's used by all testSuites and all
test cases under each suite. But current cluster config (3 broker, 1 zookeeper,
1 consumer, 1 producer) does not apply to migration test, so I have to create a
new one (1 07 zookeeper, 1 08 zookeeper, 3 07 brokers, 3 08 brokers, 1 07
producer, 1 migration tool, 1 08 consumer),
But the current replication_testSuite cannot work with this configration, I
have to delete it temporarily. (I've talked with John to enable local cluster
configuration instead of just global one)
I created new "role"s of "broker07", "zookeeper07" and
"producer_performance07", and changed a few files in the system test framework.
Currently it is still not working, continuing on it...
Please help review the migration tool itself

> Key: KAFKA-344
> URL: https://issues.apache.org/jira/browse/KAFKA-344
> Project: Kafka
> Issue Type: Sub-task
> Components: core
> Affects Versions: 0.8
> Reporter: Jun Rao
> Assignee: Yang Ye
> Labels: tools
> Fix For: 0.8
>
> Attachments: kafka_344_draft.patch
>
> Original Estimate: 336h
> Remaining Estimate: 336h
>
> Since 0.8 is a non-backward compatible release, we need a migration tool. One
> way to do that is to have a tool that can mirror data from an 0.7 Kafka
> cluster into an 0.8 Kafka cluster. Once the mirror is set up, we can then
> first migrate the consumers to the 0.8 cluster, followed by the producers.
> After that, we can decommission the 0.7 cluster.
