+if you need the Dmaap connector support, before running Opendaylight, set DMAAP_BASE_URL as environment variable.
+For example, if the base url of your Dmaap server is "https://dmaap-mr:30226", then::
+
+ export DMAAP_BASE_URL=https://dmaap-mr:30226
+
+if your Dmaap server provides https connection through a self-signed certificate, do not forget to add the certificate
+to the JAVA truststore::
+
+ echo -n | openssl s_client -showcerts -connect dmaap-mr:30226 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > /tmp/dmaap.crt
+ keytool -import -v -trustcacerts -alias dmaap -file /tmp/dmaap.crt -keystore /etc/ssl/certs/java/cacerts -keypass changeit -storepass changeit -noprompt
+
+where dmaap-mr:30226 is the url of your Dmaap server.
+
+Then run in karaf::
+
+ feature:install odl-transportpce-dmaap-client
