    <description>&lt;P&gt;I am trying to install HDF 3.3.1 (NIFI) to my existing HDP 3.1 cluster with Ambari 2.7.3. (&lt;A href="https://supportmatrix.hortonworks.com/" target="_blank"&gt;https://supportmatrix.hortonworks.com/&lt;/A&gt;)&lt;/P&gt;&lt;P&gt;I have followed all the steps in the documentation (Installing HDF Services on an Existing HDP Cluster), installed HDF management pack, ambari server restart = yes but I still cannot add HDF services through Add Service Wizard. Nothing to choose in 'Choose Serivce' .. Also cannot find space to update HDF Base URL&lt;/P&gt;&lt;P&gt;Can someone help me with this issue.&lt;/P&gt;&lt;P&gt;Thanks.&lt;/P&gt;</description>

      <description>&lt;P&gt;I think my mpack wasn't installed properly. So I uninstalled and reinstalled again. Now it is working fine.&lt;/P&gt;&lt;P&gt;I followed the steps from Derek's answer from the link below:&lt;/P&gt;&lt;P&gt;&lt;A href="https://community.hortonworks.com/questions/208084/remove-hdf-mpack.html"&gt;https://community.hortonworks.com/questions/208084/remove-hdf-mpack.html&lt;/A&gt;&lt;/P&gt;&lt;P&gt;Thanks,&lt;/P&gt;</description>
