ClassNotFoundException for Zookeeper while building Storm

由 余生颓废 提交于 2019-12-02 00:53:14

It seems that the key is here:

Caused by: java.lang.ClassNotFoundException: org.apache.zookeeper.server.NIOServerCnxn$Factory

This seems caused by using the version 3.4.5 of zookeeper. Have you tried a downgrade to, maybe version 3.3.6?

The branch-3.3 contains that Inner Class NIOServerCnxn$Factory but the branch-3.4 has the NIOServerCnxnFactory instead

It seems that final jar is missing zookeeper. Try adding this:

   <dependency>
        <groupId>org.apache.flume</groupId>
        <artifactId>flume-ng-core</artifactId>
        <version>${flume.version}</version>

            </exclusion>
        </exclusions>
    </dependency>


<dependency>
  <groupId>org.apache.zookeeper</groupId>
  <artifactId>zookeeper</artifactId>

</dependency>
<dependency>
  <groupId>org.slf4j</groupId>
  <artifactId>slf4j-log4j12</artifactId>
  <version>1.5.8</version>
</dependency>

to your pom.xml.

If it doesn't help issue :

mvn dependency:tree

and send me output.

The below POM works for me -

I have also faced the same issue, the problem i noticed in my case is: I am using storm-9.0.1 with Zookeeper 3.4.5.

By change my zookeeper to 3.3.6 or by changing the storm to 9.0.2,My problem have solved.

So Storm-9.0.1 is compatibility with Zookeeper 3.3.6 and Storm 9.0.2 is compatibility with Zookeeper 3.4.5

After some days of banging my head I decided to change the aproach, aparently Eclipse could run the project as it was without any issue.

Creating an uberjar from eclipse and puting all the referenced jars in the project's lib folder and then running the uberjar in the server using java -jar solved the issue.

Not a good solution and I never understood why maven couldn't run the project but it works.
