<div class="moz-cite-prefix">Hi Andrew,<br>
<br>
Many thanks for prompt reply. The issue was exactly what you
described.<br>
<br>
I created alternatives for sahara-api, sahara-engine and sahara,
and left _sahara-subprocess. This is how juno was working hence I
kept the setup same.<br>
<br>
Now I created alternatives for _sahara-subprocess and it solved
the issue.<br>
<br>
Thanks,<br>
Amardeep<br>

<div>It looks like Sahara engine tries to run
"_sahara-subprocess" executable of other version. Sahara uses
real subprocesses to gain all benefits of multithreading
(greenthreads are not enough). It assumes that there is
"_sahara-subprocess" executable in the same folder with sahara
engine. They must be the same version. </div>

<br>
I am trying to configure<b> Openstack Sahara </b><b>Kilo</b>
release on existing <b>Openstack </b><b>Juno</b> setup.
After successful integration of services and dashboard
everything works smooth until it start creating cluster. <br>
<br>
- Create Node Group Templates for Plugin "vanilla" Hadoop
Version "2.6"<br>
- Create Cluster Template for Plugin "vanilla" Hadoop
Version "2.6"<br>
- Used sahara-image-elements and created qcow image of
ubuntu for version 2.6<br>
- Register image with correct username "ubuntu"<br>
- Generate key pair and attached to cluster<br>
- Launch Cluster<br>
<br>
When cluster launches it creates instances with networking
enabled. I can ping the nodes and ssh into them using
keypair generated, but for some reason controller is
unable to run ssh commands. The following error comes in <b>sahara-all</b><b>.log</b>(attached)<br>
