Hi folks,
Recently we run into an odd issue that some partition's latest offset
becomes 0. Here's the snapshot of the Kafka Manager. As you can see
partition 2 and 3 becomes zero.
*Partition*
*Latest Offset*
*Leader*
*Replicas*
*In Sync Replicas*
*Preferred Leader?*
*Under Replicated?*
0
2
:org.apache.kafka.common.errors.NotLeaderForPartitionException: This
server is not the leader for that topic-partition.
(kafka.server.ReplicaFetcherThread)
And after restart that controller, everything works again.

Hi folks, Rajiv, Jun,
I'd like to bring up this thread again from Rajiv Kurian 3 months ago.
Basically we did the same thing as Rajiv did. I upgraded two machines (out
of 10) from 0.8.2.1 to 0.9. SO after the upgrade, there will be 2 machines
in 0.9 and 8 machines in 0.8.2.1. And initially it all w
Hi folks,
We just finished the upgrade from 0.8.2 to 0.9 with the instructions in
Kafka web site (that set the protocol version as 0.8.2.x in Kafka server
0.9).
After the upgrade, we want to try the producer with SSL endpoint, but never
worked. Here's the error:
~/kafka_2.11-0.9.0.0$ ./bin/kafka-c
ssues with 0.9.0 and SparkStreaming. However,

Forgot to mention is that the Kafka version we're using is from Aug's Trunk
branch---which has the SSL support.
Thanks again,

Hi folks,
We have a 10 node cluster and have several topics. Each topic has about 256
partitions with 3 replica factor. Now we run into an issue that in some
topic, a few partition (< 10)'s leader is -1 and all of them has only one
synced partition.

Hi,
We're running the Trunk version of Kafka (for its SSL feature) and recently
I'm trying to enable the kafka manager with it.
After enabling that, I find out some machine's Kafka Server is dead.
Looking at the server.log, it has the following logs.

Hi all,
I'm using the Kafka.Net library for implementing the Kafka Producer.
One issue I find out is that sometimes it reads the response from kafka
server, which indicates a huge message size 386073344. Apparently something
must be wrong.
But I'm not sure if it's a special flag that Kafka.net
Hi folks,
I tried to clone the latest version of kafka truck and try to enable the
SSL. The server.properties seems not having any security related settings,
and it seems there's no other config file relevant to SSL either.
So may I know is this feature ready to use now in truck branch?
BTW, we're
Hi Everyone,
I have a question that hopes to get some clarification.
In a Kafka cluster, does every broker have the complete view of the
metadata information?
What's the best practice for aproducer to send metadata request? Is it
recommended to send it to all brokers or just one broker?
In our sce
Hi Everyone,
We're trying the deploy the Kafka behind the network balancer and we have
created the port map for each Kafka brokers under that network balancer--we
only have one public IP and the Kafka clients are in other system and thus
cannot access the brokers via internal IP directly.
So for e
