Hi Sai, I've had the same error message with a Ubuntu 14.04 host system. I'm yet to get it fully working but here's my progress so far. I'm thinking it may be a resolver / route issue, but haven't looked into it enough. For the error message above, I edited the ansible script in incubator-metron-Metron_0.1BETA_rc7/deployment/roles/elasticsearch/tasks/configure_index.yml to use the ip of the host. e.g. http://192.168.66.121:9200/. This needed to be done for 'Wait for Green Index Status' and the task below it. After this change, the install seemed to complete successfully, however kibana was turning up blank. This was resolved by: 1) edit the elasticsearch parameter at /usr/metron/0.1BETA/metron-ui/lib/public/config.js to be elasticsearch: 'http://<ip>:9200', 2) add the following to /etc/elasticsearch/elasticsearch.yml http.cors.allow-origin: "/.*/" http.cors.enabled: true 3) restart elasticsearch /etc/init.d/elasticsearch restart At this stage, I am seeing the pcaps traversing through storm, however am getting getting errors in the enrichment topology forwarding the data to elasticsearch. I'm still looking into this. Hope this helps, Ryan ... View more
