Bug 1138800

release version:
vt2.2

+++ This bug was initially created as a clone of Bug #1115957 +++

Description of problem:

I'm trying to setup ovirt-engine-websocket-proxy on different host than engine is running. thus I don't see sense to have whole set of jboss/engine packages installed.

1. yum install ovirt-engine-setup-base ovirt-engine-websocket-proxy (see BZ1114978)
2. engine-setup

~~~
# engine-setup

and now if ovirt-engine and its deps are installed:

This is odd, IMHO it should work like this:
- check what setup plugins are present
- inform/ask user to approve setup of available plugins
- then check plugins deps/related stuff

Version-Release number of selected component (if applicable):
ovirt-engine-setup-base-3.5.0-0.0.master.20140629172257.git0b16ed7.el6.noarch
ovirt-engine-setup-plugin-ovirt-engine-common-3.5.0-0.0.master.20140629172257.git0b16ed7.el6.noarch
ovirt-engine-setup-plugin-websocket-proxy-3.5.0-0.0.master.20140629172257.git0b16ed7.el6.noarch

How reproducible:
100%

Steps to Reproduce:
1. install ovirt-engine-setup-base-3.5.0-0.0.master.20140629172257.git0b16ed7.el6.noarch ovirt-engine-setup-plugin-ovirt-engine-common-3.5.0-0.0.master.20140629172257.git0b16ed7.el6.noarch ovirt-engine-setup-plugin-websocket-proxy-3.5.0-0.0.master.20140629172257.git0b16ed7.el6.noarch
2. run engine-setup
3.

Actual results:
failure

Expected results:
should work without whole java/jboss/engine stuff

Sorry, I'm not able to reproduce.

Installing only ovirt-engine-websocket-proxy (and its dependencies) after patch 
http://gerrit.ovirt.org/#/c/29456/ everything seams to work correctly.

On that VM, from ovirt repo, I've only:

[stirabos@f19td4 ~]$ yum list installed | grep ovirt
libgovirt.x86_64                 0.1.0-1.fc19       @updates                    
                                                    @ovirt-3.5-pre              
ovirt-engine-lib.noarch          3.5.0-0.0.master.20140629172304.git0b16ed7.fc19
                                                    @ovirt-3.5-pre              
ovirt-engine-setup-base.noarch   3.5.0-0.0.master.20140629172304.git0b16ed7.fc19
                                                    @ovirt-3.5-pre              
ovirt-engine-setup-plugin-websocket-proxy.noarch
                                                    @ovirt-3.5-pre              
ovirt-engine-websocket-proxy.noarch
                                                    @ovirt-3.5-pre              
ovirt-release35.noarch           001-0.0.alpha1     @/ovirt-release35           
[stirabos@f19td4 ~]$ 

and nothing at all about java

[stirabos@f19td4 ~]$ yum list installed | grep java
[stirabos@f19td4 ~]$ 


and setup completes correctly.

Can you please add the list of ovirt rpm on your setup?

I do not verify patches but only builds. So when your patch is incorporated into new build, please change status for ON_QA for verification. Thanks.

Ok, patch http://gerrit.ovirt.org/#/c/29456/ seams also to solve this.

ovirt-engine-setup-plugin-ovirt-engine-common checks Java presence for product options that depends on that, ovirt-engine-websocket-proxy doesn't need Java but ovirt-engine-setup-plugin-websocket-proxy also doesn't depends from ovirt-engine-setup-plugin-ovirt-engine-common.
I think that on you test system you probably have also ovirt-engine-setup-plugin-ovirt-engine-common and so the problem. You simply don't need it as you also don't need the Java stuff or the DB stuff for the WebSocket proxy alone.

Same comment as https://bugzilla.redhat.com/show_bug.cgi?id=1114978#c11

--- Additional comment from Jiri Belka on 2014-07-16 03:14:01 EDT ---

Not merged probably, like BZ1114978, see there.

--- Additional comment from Simone Tiraboschi on 2014-07-16 03:59:37 EDT ---

patch 29456 (http://gerrit.ovirt.org/#/c/29456/) should solve this too and it was already merged: we just need to wait for a new tagged release before changing to ON_QA, sorry for that.
