Hi List,
I'm new to kafka, feel sorry if this has been asked, I didn't figure out
my answer by googling, so asked here. Thanks in advance!
I'm following the kafka quick start
http://kafka.apache.org/documentation.html#quickstart
and managed setup a kafka cluster with two brokers, which
just simply tried artifact kafka_2.10:0.8.1.1 as suggested in
https://issues.apache.org/jira/browse/KAFKA-1454 but got the error written
above
now I've cloned the repo and compiled with
./gradlew jar = success
./gradlew -PscalaVersion=2.10.0 jar = success
./gradlew -PscalaVersion=2.11.0 jar =
Hi Chengwei,
What do you see in the Kafka server logs? This may help you diagnose the
failure.
Cheers, Robert

There is no direct way. You can try getting the last offset (the offset of
the next to be appended message) using the getOffsetBefore api and then
using that offset - 1 to fetch.

So for example to create real load balance between broker I can:

Hi All,
I'm looking to connect with someone who's got about 6 months of Kafka
experience looking to build on it with a contract opportunity I have.
Please let me know if you'd be interested.

In the new consumer design the partitioning algorithm can be customized by
the user:

Would that fit your use case?

I think that in design we must point out that co-ordinator also must analize
connection graph and must map consumers to broker with minimal network
overhead...

Hi team,
Assume I am using a synchronous producer and it has the following default
properties:
message.send.max.retries
3
retry.backoff.ms
100
I use java api Producer.send(message) to send a message.
While send() is being called, if the brokers are shutdown, what happens?
send()
Hi,
Assume I am using a synchronous producer and request.required.acks is set to 0
(default).
When java api Producer.send(message) returns, is the message acknowledged? Is
there any
chance of message loss in the case? Thanks.

We have 4 producers (for 4 topics) within one JVM and all of them
configured with same broker list. Each one of the producer has client.id
configured as topic name. When I see the JMX console, I see that

We have recently changed the “message.max.bytes” to 2MB and rebooted all
the brokers at once. After this, we are getting

consumer side. How do I fix this, I have restarted producer and
consumer

No there will be no ACKs sent back, messages may failed to reach the broker
but producers will not be notified in this case.

This exception is usually normal and transient upon broker restarts. Do you
still see them after restarting the brokers for a while?

That's just a warning and the producer will retry. Was there an error
(which means all retries failed)?

It is possible that when I tried this ticket initially there was something
environmental in my build process causing it to appear to work.
I reopened the ticket.
I will go back through it again on a few different environments and in more
detail and post results either way.
