            <title>[NETVIRT-33] ERROR Log Observations - CSIT (sal datastore related)</title>
                <link>https://jira.opendaylight.org/browse/NETVIRT-33</link>
                <project id="10144" key="NETVIRT">netvirt</project>
                    <description>&lt;p&gt;The 3node Netvirt Openstack Tests are failing, In this report, we would like to capture the clustering related errors seen in karaf log for further analysis.&lt;/p&gt;

&lt;p&gt;Some datastore related errors observed in karaf.log from all the 3 nodes in Netvirt.  I guess, not all of the messages are actual failures, But it will be better to have some explanation for the failure being reported.&lt;/p&gt;

                            <comment id="36195" author="arthi.b@hcl.com" created="Fri, 15 Jul 2016 13:29:17 +0000"  >&lt;p&gt;Hi Venkat,&lt;/p&gt;

&lt;p&gt;&#8226; While pushing Entity Owner configuration snapshot, these errors are been occurred. Since there is no property set at the beginning, the property is null and thus it throws an error.&lt;/p&gt;

&lt;p&gt;&#8226; The configuration ID &#8220;org.opendaylight.controller.cluster.entity.owner.selection.strategies&quot; is used to fetch the configuration object. Since there is no configuration object available, it returns a new configuration object with property null.&lt;br/&gt;
REF:: &lt;a href=&quot;https://osgi.org/javadoc/r4v42/org/osgi/service/cm/ConfigurationAdmin.html#getConfiguration(java.lang.String&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://osgi.org/javadoc/r4v42/org/osgi/service/cm/ConfigurationAdmin.html#getConfiguration(java.lang.String&lt;/a&gt;)&lt;/p&gt;

&lt;p&gt;&#8226; We must have a configuration file (.cfg) in /etc folder. Since that file is missing, we manually added that file and tried it. The error is not produced.&lt;br/&gt;
