I wish this helpful for you It looks that you are trying to use spark 2.X with library from spark 1.5...
Fix your --packages option passing valid library version. You can get the possible versions directly from the maven repository.

fixed the issue. Will look into that further Add the dependency to zeppelin context "z". Heres an example of adding the sparkcsv package
code :
%dep
z.load("com.databricks:spark-csv_2.11:1.3.0")

will be helpful for those in need i commented the below dependencies. Added spark-streaming-kafka_2.10 and added kafka_2.10-0.8.1.1 jar to referenced libraries in eclpise directly by click on buildpath -> configure build path -> External Jars. This resolved the issue.
code :
<!-- dependency>
  <groupId>org.apache.kafka</groupId>
  <artifactId>kafka_2.10</artifactId>
  <version>0.8.1.1</version>
  <scope>compile</scope>
  <exclusions>
    <exclusion>
      <artifactId>jmxri</artifactId>
      <groupId>com.sun.jmx</groupId>
    </exclusion>
    <exclusion>
      <artifactId>jms</artifactId>
      <groupId>javax.jms</groupId>
    </exclusion>
    <exclusion>
      <artifactId>jmxtools</artifactId>
      <groupId>com.sun.jdmk</groupId>
    </exclusion>
  </exclusions>
 </dependency> -->

 <!--<dependency>
<groupId>org.apache.kafka</groupId>
<artifactId>kafka-clients</artifactId>

I hope this helps you . I solved my problem. It was due to my groupId, artifactId and version were the same as one of my dependencies.
code :
<groupId>org.apache.spark</groupId>
<artifactId>spark-streaming_2.11</artifactId>
<version>2.1.1</version>
<dependency>
  <groupId>org.apache.spark</groupId>
  <artifactId>spark-streaming_2.11</artifactId>
  <version>2.1.1</version>
</dependency>
