title: HBase connection exception
body: <p>I try to run HBase in a Pseudo-Distributed mode. But it doesn't work after I set hbase-site.xml. </p>
  
  <p>Each time I try to run a command inside hbase shell I get this error:</p>
  
  <blockquote>
    <p>ERROR:

    org.apache.hadoop.hbase.ZooKeeperConnectionException:
