Hello all, I am a newbie for elasticsearch, though have experience on solr... I have been trying to set up elasticsearch for running some tests, but i keep getting interesting errors while installing the jdbc river, by using the steps here: [https://github.com/jprante/elasticsearch-river-jdbc/wiki/Quickstart](https://github.com/jprante/elasticsearch-river-jdbc/wiki/Quickstart) The first error occurs after installing the plugin and starting up the elasticsearch, as below : [2013-07-25 10:29:19,225][INFO][node] [Burner] {0.90.2}[26599]: initializing ...
