Java Compiler Cannot Find Kafka Class

Question

I'm having problem using the last answer of this question in my Java code. Kafka: Get broker host from ZooKeeper

Specifically, it fails finding the last argument on this line:

ZkClient client = new ZkClient("localhost:2181", 10000, kafka.utils.ZKStringSerializer);

I'm using Maven and these are the dependencies in the pom.xml if it matters.

<dependencies>
        <dependency>
                <groupId>org.apache.kafka</groupId>
                <artifactId>kafka_2.11</artifactId>
                <version>0.8.2.2</version>
        </dependency>
        <dependency>
                <groupId>com.101tec</groupId>
                <artifactId>zkclient</artifactId>
                <version>0.7</version>
        </dependency>
</dependencies>

Did you get a compile time issue? – Omkar Puttagunta Dec 04 '15 at 06:07 — Omkar Puttagunta, Dec 04 '15 at 06:07

You have to use like this

ZkClient client = new ZkClient("localhost:2181", Integer.MAX_VALUE,10000, kafka.utils.ZKStringSerializer$.MODULE$);

kafka.utils.ZKStringSerializer is a scala object. To use scala object in java you have to use like above.

Thanks! It works! I would have never figured that out since I'm still a newbie in Scala. – shinkou Dec 04 '15 at 14:30
