With the ip -> broker id mapping: We've got 3 servers with three ip's and id's 1, 2, 3. The 3 servers kept the ip's but the broker id's switched around so something like: 192.168.0.1 -> 1 192.168.0.2 -> 2 192.168.0.3 -> 3 Then they all stopped and came back as: 192.168.0.1 -> 2 192.168.0.2 -> 3

Is there a way to know when I've reached the end of a partition (consumed all messages) when using the high-level consumer?

2015-05-08 Thread James Cheng
Hi, I want to use the high level consumer to read all partitions for a topic, and know when I have reached "the end". I know "the end" might be a little vague, since items keep showing up, but I'm trying to get as close as possible. I know that more messages might show up later, but I want to k

Issue with kafka-topics.sh tool for adding new partitions with replica assignment

2015-05-08 Thread Stefan Schadwinkel
Hi, with Kafka 0.8 it is possible to add new partitions on newly added brokers and supply a partition assignment to put the new partitions mainly on the new brokers (4 and 5 are the new brokers): bin/kafka-add-partitions.sh --topic scale-test-001 \ --partition 14 \ --replica-assignment-list 4:5,4

Jamie,       Once the patch gets in you can configure kafka brokers with ssl configs and similarly you can configure producer and consumer with ssl both will negotiate a ssl connection once its established rest of the communication will happen over ssl. I am not sure about the timeline but we ar

Thank you Harsha for the reply. Will the patch work with 0.8.2.1? So the general logic is that we write an agent that sends message via https and then may be a servlet using Kafka produce class to authenticate with kafka server on ssl port and so on When will the full implementation be avail

Also it would be great to know if you see the same issue when you don't have different ip -> broker id mapping. Also it would be great if you can explain " different ip -> broker id mapping" mean as Becket said. Thanks, Mayuresh On Fri, May 8, 2015 at 9:48 AM, Mayuresh Gharat wrote: > It shoul

Dan, Just to make sure I understand it correctly. What do you mean by different ip -> broker mapping? Do you mean you changed your broker ip? We have different mechanism in and producer to get the cluster information. Consumer get all the information from Zookeeper while producer has to talk to br

Hi Mayuresh, Yes, the broker is up and accepting connections. Multiple consumers are consuming off topics on the broker. Also I am seeing the issue only with this particular version (2.11-0.8.2.1). It worked fine with the beta that I was using earlier. On Fri, May 8, 2015 at 12:45 PM, Mayuresh G

It should do a updateMetadataRequest in case it gets NOT_LEADER_FOR PARTITION. This looks like a bug. Thanks, Mayuresh On Fri, May 8, 2015 at 8:53 AM, Dan wrote: > Hi, > > We've noticed an issue on our staging environment where all 3 of our Kafka > hosts shutdown and came back with a different

Is X.X.X.X:9092 up and accepting connections? I am confused aas in why is it not connecting some other broker if connection to this broker fails. Can you check if the broker is up? The way it works is the consumer will send a ConsumerMetadataRequest to one of the brokers and get the offsetmanager

Hi, We've noticed an issue on our staging environment where all 3 of our Kafka hosts shutdown and came back with a different ip -> broker id mapping. I know this is not good and we're fixing that separately. But what we noticed is all the consumers recovered but the producers got stuck with the fo
