I am a new user of Elasticsearch and Logstach. I have downloaded new versions of these tools (directly from ElasticSearch download page, exacly: "Elasticsearch 1.0.0" and "Logstash 1.3.3"). After running both I noticed that Elasticsearch throws such exceptions like below. Is it possible to run these tools together? How? Which version of Logstach I have to use with ElasticSearch 1.0? I can't use lower version of ElasticSearch - I need built-in snapshot/restore module. _[2014-02-14T17:17:49.821] WARN: org.elasticsearch.discovery.zen.ping.unicast: [Rasputin, Illyana] failed to send

For now, you can use the elasticsearch\_http output (instead of elasticsearch) and you should be able to get LS 1.3.3 going with ES 1.0. For example: output { elasticsearch\_http { host =\> "localhost" } } -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
