[VTN-50] OpenStack support doesn't work.

Blocks — Thu, 19 Oct 2017 21:25:25 +0000

I observed that OpenStack support didn't work correctly when I installed VTN features after other features.

feature:install odl-adsal-compatibility-all odl-openflowplugin-all odl-vtn-manager-all

Specifically, I observed that REST API of Neutron interface didn't work at all.
For example, GET requests for neutron/networks returned the response code 500 (Internal Server Error) and an error message, although it should return the response code 200 and network information.

curl --user "admin":"admin" -H "Accept: application/json" -H \
"Content-type: application/json" -X GET \
http://localhost:8080/controller/nb/v2/neutron/networks

I observed this issue on both Helium and Helium SU1.

Workaround
==========

It seems to me that if we install VTN features firstly, we don't face the issue.

feature:install odl-vtn-manager-all odl-openflowplugin-all odl-adsal-compatibility-all

How to reproduce the issue
==========================

1. Run Karaf.

$ bin/karaf

2. Install VTN features.

feature:install odl-adsal-compatibility-all odl-openflowplugin-all odl-vtn-manager-all

3. Send a GET request to Neutron interface.
curl --user "admin":"admin" -H "Accept: application/json" -H \
"Content-type: application/json" -X GET \
http://localhost:8080/controller/nb/v2/neutron/networks

The expected response message of the GET request is as follows:

{ "networks" : [ ] }

Error log message
=================

When I sent a GET request to Neutron interface, Helium output the following ERROR message into karaf.log.

ERROR | -bio-8080-exec-1 | [/controller/nb/v2/neutron] | 309 - org.apache.juli.extras - 7.0.53.v201406060720 | StandardWrapper.Throwable
java.lang.NoClassDefFoundError: org/eclipse/persistence/jaxb/rs/MOXyJsonProvider

Failure example
===============

I observed the issue when I installed features as follows:

[Failure 1]
feature:install odl-adsal-compatibility-all odl-openflowplugin-all odl-vtn-manager-all

[Failure 2]
feature:install odl-adsal-all odl-adsal-northbound
feature:install odl-adsal-compatibility-all odl-openflowplugin-all odl-vtn-manager-all

Successful examples
===================

I didn't observe the issue when I installed features as follows:

[Success 1]
feature:install odl-vtn-manager-all odl-openflowplugin-all odl-adsal-compatibility-all

[Success 2]
feature:install odl-vtn-manager-neutron
feature:install odl-vtn-manager-all
feature:install odl-openflowplugin-all
feature:install odl-adsal-compatibility-all
