Twitter stream error- A plugin had an unrecoverable error. Will restart this plugin.

[nikulkarni]

Updated twitter.conf with correct credentials. However when I run /elk/logstash-1.4.2/bin/logstash -f twitter.conf, I get below error. I truncated the output a bit for brevity. So it looks like twitter is responding with JSON that the plugin is not able to parse? Am I missing anything?

Using milestone 1 input plugin 'twitter'. This plugin should work, but would benefit from use by folks like you. Please let us know if you find bugs or have suggestions on how to improve this plugin.  For more information on plugin milestones, see http://logstash.net/docs/1.4.2/plugin-milestones {:level=>:warn}
