Jun Rao commented on KAFKA-329:
-------------------------------
Prahsanth,
I was trying to figure out why
ZookeeperConsumerConnectorTest.testCompressionSetConsumption() failed. For
that, I added a bit more logging in DefaultEventHandler. However, after the
logging was added, the test seems to pass. I suspect this is probably due to a
time-dependant transient failure. I checked in the extra logging as a trivial
change. So, if you can fix the remaining comments and there is no more unit
test failure, you can just commit the patch without further review.
> Remove the watches/broker for new topics and partitions and change create
> topic admin API to send start replica state change to all brokers

> Currently in 0.8, all brokers register a watch on /brokers/topics and
> /brokers/topics/[topic] for all topics in a Kafka cluster. The watches are
> required to discover new topics.
> There is another way this can be achieved, as proposed here -
> https://cwiki.apache.org/confluence/display/KAFKA/Kafka+replication+detailed+design+V2#KafkareplicationdetaileddesignV2-Createtopic
> Basically, the create-topic admin command sends start-replica state change
> request to all brokers in the assigned replicas list.
