POM error on Ubuntu
<p>I am new to Maven. I am trying to install Apache Zeppelin for Spark on Ubuntu which is installed on a VM. For that I need to have JAVA and MAVEN installed on the machine. I ran the below statement</p>

<pre><code>sudo apt-get install maven
</code></pre>

<p>It ran successfully. I checked the version (Successful)</p>

<pre><code>hduser@HDPMaster:/usr$ mvn -version
