Hi,
My name is Paul. Previously I was using storm 0.10.0 and now have to upgrade to
the latest 2.2.0.
I am using flux. But it isn't working. This is my config:
name: "AuditLogConsumerTopology"
components:
- id: "kafkaConfigBuilder"
className: "org.apache.storm.kafka.spout.KafkaSpoutConfig$Builder"
constructorArgs:
# bootstrap servers
- "localhost:9092"
# topics
- ["topic"]
#Spout Config
- id: "SpoutConfig"
className: "org.apache.storm.kafka.spout.KafkaSpoutConfig"
constructorArgs:
# brokerHosts
- ref: "kafkaConfigBuilder"
properties:
- name: "group.id"
value: "test-group"
- name: "key.deserializer"
value: "org.apache.kafka.common.serialization.StringDeserializer"
- name: "value.deserializer"
value: "org.apache.kafka.common.serialization.StringDeserializer"
config:
topology.workers: 1
topology.max.spout.pending: 1000
topology.acker.executors: 1
topology.executor.send.buffer.size: 16384
topology.executor.receive.buffer.size: 16384
topology.transfer.buffer.size: 32
zookeeperHost: "localhost"
zookeeperBasePath: "platformaudit"
kafka.broker.properties:
#bootstrap.servers: "localhost:9092"
metadata.broker.list: "localhost:9092"
request.required.acks: "1"
topic: "topic"
spouts:
- id: "TestSpout"
className: "org.apache.storm.kafka.spout.KafkaSpout"
parallelism: 1
constructorArgs:
- ref: "SpoutConfig"
bolts:
- id: "TestBolt"
className: "auditlog.TestBolt"
parallelism: 1
constructorArgs:
#index
- "auditlog"
#type
- "_doc"
#hostname
- localhost
#port
- 9200
streams:
- name: "TestSpout --> TestBolt"
from: "TesstSpout"
to: "TestBolt"
grouping:
type: SHUFFLE
My changing the configuration by referring to the actual storm consumer 2.2.0
code I was able to make this yaml flux file.
However I am unable to specify any properties from this yaml file for the
consumer.
I tried giving "group.id" and it gives an errror:
Exception in thread "main" java.lang.NoSuchFieldException: groupId

at org.apache.storm.flux.Flux.main(Flux.java:119)
Without specifying properties the topology does get submitted but it throws an
error in the spout saying:
java.lang.RuntimeException: org.apache.kafka.common.config.ConfigException:
Missing required configuration "key.deserializer" which has no default value.

I went through a bit of the source code and found this. The properties aren't
there in the "org.apache.storm.kafka.spout.KafkaSpoutConfig" file but in the
"ConsumerConfig" file. So when flux tries to get the field name given in the
properties file it fails.
Previously in version 0.10.0 the configuration fields were available in the
"storm.kafka.SpoutConfig" file itself.
Can I please get some help on how to resolve this issue? The flux kafka spout
example at "https://storm.apache.org/releases/2.2.0/flux.html"; is also wrong. I
am not sure if it has been updated.
Best Regards,
Paul Jose
