Github user anandsubbu commented on the issue: https://github.com/apache/metron/pull/817 If the install fails the first time due to ES being down, then we WARN and move on. If ES service comes up later, the admin needs to install the templates subsequently by using 'Ambari -> Metron -> Service Actions -> Elasticsearch Template Install' option. Alternatively s/he can also stop the Indexing service and start again so the template will be installed (Note that calling "restart" on the Indexing service will not trigger the template installation)
