title: Use hyphen in impala database name
body: <p>I have a script which directly requires the creation of impala databases using hyphen in the database name.</p>
  
  <p>I am not able to do the same in impala shell using the below command.</p>
  
  <pre><code>******** default&gt; create database test-1;
  Query: create database test-1
  ERROR: AnalysisException: Invalid database name: test-1
  </code></pre>
  
  <p>Even back tick does not help</p>
  
  <pre><code>******** default&gt; create database `test-1`;
  Query: create database `test-1`
  ERROR: AnalysisException: Invalid database name: test-1
  </code></pre>
