  <p>But none of the stats are getting collected. In hbase both tsdb and tsdb-uid are empty.</p>
  
  <pre><code>hbase(main):002:0&gt; scan 'tsdb'
  ROW                                                          COLUMN+CELL

  <p>If someone could help me with this, will be much appreciated. </p>
  
  <p>All Hadoop based technologies are very difficult to install and configure. It took me a week to get my head around this and I am running the tcollector for 24 hrs and still no data in TSDB.</p>
  
  <p>Many thanks,</p>
