In the Amsterdam version, when running the Robot HC on SDC running in a multi-node Kubernetes deployment, the SDC-DE HC fails with the message "U-EB Cluster is not available"

This problem has been raised by someone in the onap-discuss mailing list, in this thread: https://www.mail-archive.com/onap-discuss@lists.onap.org/msg08329.html, and the identified root cause for the failure and proposed solution for this error.

Solution is to change the "ueb_url_list" and "fqdn" fields in /dockerdata-nfs/onap/sdc/environments/AUTO.json, where the lines below should show the dmaap service.ns name identifier instead of the external k8s node IPs, since the containers created can reach the internal dmaap service.ns (i.e. dmaap.onap-message-router with service name being "dmaap" and namespace being "onap-message-router") instead.

To solve this, line needs to be changed in https://gerrit.onap.org/r/gitweb?p=oom.git;a=blob;f=kubernetes/config/docker/init/config-init.sh;h=a65a11e89e8d61f21df1b2c11f6576794e14d34e;hb=refs/heads/amsterdam#l264
