title: nifi and kylo both in cluster mode
body: <p>i am trying to run Kylo and Nifi both in cluster mode. </p>
  
  <ol>
  <li>Nifi I am using doesn't come packaged with Kylo. I have installed nifi and kylo separately.</li>
  <li>I am able to run Nifi in cluster mode (2 servers) and front ended it with a LB. LB has its own DNS. I am able to access it, and both nifi nodes identify each other.</li>
  <li>I am able to install kylo in cluster mode and same way, i have front ended it with LB. </li>
  <li>both nifi and kylo are https. I am using SAN certificate and it all is working fine.</li>
  <li>although my infra is not internet facing (intranet), i have procured CA certs (not using self signed).</li>
  <li>now i am trying to integrate Kylo  with Nifi, so I control flows in better ways.</li>
  <li>I am now on the step where I have to integrate kylo services with nifi.</li>
  </ol>
  
  <p><strong>Now issue is.</strong></p>
  
  <ol start="8">
  <li>I am trying to make kylo ware of nifi, so I can use it. as per my assumption, kylo both nodes (k1 and k2) should point to LB of nifi and not directly to both nodes of nifi (n1 and n2).</li>
  <li><p>i am following steps mentioned under (but not completely), as i am not relate it to my situation <a href="https://kylo.readthedocs.io/en/v0.10.0/security/ConfigureNiFiWithSSL.html" rel="nofollow noreferrer">https://kylo.readthedocs.io/en/v0.10.0/security/ConfigureNiFiWithSSL.html</a></p></li>
  <li><p>i am wondering how to generate keystore kylo service, it seems toolkit way is not working :( . it does generate the file, but still no communication with Nifi.</p></li>
  </ol>
  
  <p>one strange thing, I am able to connect K1-N1 and K2-N2 (k1, k2 are 2 nodes of Kylo, n1,n2 are 2 nodes of nifi). But i am not able to connect Kylo to LB of Nifi. Unless i do that, i think I am not doing pure HA.</p>
  
  <p>error i am getting on UI is, backend is not helpful either. it just shows not able to connect. although i am able to access LB dns from browser, and it works perfectly fine. => <a href="https://i.stack.imgur.com/J77fi.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/J77fi.png" alt="enter image description here"></a></p>
