We are using storm Kafka integration where a Spout reads from a Kafka topic.
Following is the version of storm, Kafka and zookeeper we are using.
Strom : apache-storm-0.9.2-incubating
Kafka : kafka_2.8.0-0.8.1.1
Zookeeper : zookeeper-3.4.6
I am facing following issues at spout.
1)The messages gets failed even if the average time taken is less than max.topology.timeout value, also we aren’t getting any exceptions at any of the bolt.
2)A topology is finally emitting to the Kafka producer i.e. some other topic, but the messages are getting duplicated due to replay issues.
3)The consumer group is isn’t working properly for storm Kafka integration.
a.When we give same group id to the Kafka consumer of different topology but still both are reading same messages.
b.If we have 2 different consumer with different consumer group id in different topology it works fine if both topologies are deployed at the same time, but doesn’t if we deploy one of them after some of the message are already loaded in the topic and read by the first topology.
Kindly help me with above points as it is hampering the overall scope of the project and also time lines.
