title: AuthorizationException in Impala
body: <p>I'm getting this error:</p>
  
  <pre><code>ERROR: AuthorizationException: User 'hdfs' does not have privileges to access: default.*
  </code></pre>
  
  <p>When I try and run this simple command in impala-shell:</p>
  
  <pre><code>show tables;
  </code></pre>
  
  <p>Does anyone know how I might get the required privileges? Thanks.</p>
  
  <p>Edit: I've just found the Impala app in Hue - it scrolls the same message down the screen for the admin user.</p>
