title: Triggering a paragraph in Apache Zeppelin using z.run()
body: <p>I am having some problems with Apache Zeppelin and I am not sure what I am missing, basically</p>
  
  <p>I am trying to trigger a paragraph from another paragraph in Apache Zeppelin using z.run. When I run the paragraph with z.run I get no error, but the paragraph I specified is also not run. On the other hand, if I enter the wrong paragraphID on purpose, I get an error that this paragraph doesn't exit. </p>
  
  <p>I have tried using <code>z.runParagraph</code>, <code>z.run</code> with spark and <code>z.z.run</code> with pyspark. However, when I copy the code from here <a href="https://zeppelin.apache.org/docs/0.8.0/usage/display_system/angular_frontend.html" rel="nofollow noreferrer">angular_frontend.html</a> 
  I am able to run another paragraph when filling in the paragraphID and clicking  "run paragraph". </p>
  
  <p>What I am trying is the following: </p>
  
  <pre><code>%spark 
  z.run("paragraphID")
  
  %pyspark
  print("Hello World")
  </code></pre>
  
  <p>I expect the "Hello World" will be printed, but it is not. </p>
