Hi Tatu / Scott,

Thanks for your replies. I replaced the earlier dependencies with these:

   <dependency>
    <groupId>org.apache.avro</groupId>
    <artifactId>avro-tools</artifactId>
    <version>1.6.3</version>
    </dependency>

    <dependency>
    <groupId>org.apache.avro</groupId>
    <artifactId>avro</artifactId>
    <version>1.6.3</version>
    </dependency>

    <dependency>
    <groupId>org.codehaus.jackson</groupId>
      <artifactId>jackson-mapper-asl</artifactId>
      <version>1.8.8</version>
      <scope>compile</scope>
    </dependency>

    <dependency>
    <groupId>org.codehaus.jackson</groupId>
      <artifactId>jackson-core-asl</artifactId>
      <version>1.8.8</version>
      <scope>compile</scope>
    </dependency>

And this is my app dependency tree:

I still get the same error. Is there anything specific I need to do other
than changing dependencies in pom.xml to make this error go away?
