--------------------------------
Resolution: Duplicate
> ConsumerConfig does not honor default java.util.Properties
> ----------------------------------------------------------
>
> Key: KAFKA-2184
> URL: https://issues.apache.org/jira/browse/KAFKA-2184
> Project: Kafka
> Issue Type: Bug
> Components: consumer
> Affects Versions: 0.8.2.0
> Reporter: Jason Whaley
> Assignee: Neha Narkhede
> Priority: Minor
>
> When creating a ConsumerConfig from java.util.Properties, an
> IllegalArgumentException is thrown when the Properties instance is converted
> to a VerifiableProperties instance. To reproduce:
> {code}
> package com.test;
> import kafka.consumer.ConsumerConfig;
> import java.util.Properties;
> public class ContainsKeyTest {
> public static void main(String[] args) {
> Properties defaultProperties = new Properties();
> defaultProperties.put("zookeeper.connect", "192.168.50.4:2181");
> defaultProperties.put("zookeeper.session.timeout.ms", "400");
> defaultProperties.put("zookeeper.sync.time.ms", "200");
> defaultProperties.put("auto.commit.interval.ms", "1000");
> defaultProperties.put("group.id", "consumerGroup");
> Properties props = new Properties(defaultProperties);
> //prints 192.168.50.4:2181
> System.out.println(props.getProperty("zookeeper.connect"));
> //throws java.lang.IllegalArgumentException: requirement failed:
> Missing required property 'zookeeper.connect'
> ConsumerConfig config = new ConsumerConfig(props);
> }
> }
> {code}
> This is easy enough to work around, but default Properties should be honored
> by not calling containsKey inside of
> kafka.utils.VerifiableProperties#getString
