  Here is some help for this command:
  Show cluster status. Can be 'summary', 'simple', or 'detailed'. The
  default is 'summary'. Examples:
  
    hbase&gt; status
    hbase&gt; status 'simple'
    hbase&gt; status 'summary'
    hbase&gt; status 'detailed'
  </code></pre>
  
  <p>is there anything wrong?</p>
