Everything I run a logstash file.. for example, ./logstash agent -f twitter.conf..I get the follwoing error message:

> {:exception=\>Twitter::Error::Unauthorized, :backtrace=\>["/opt/Oracle/relk/logstash/vendor/bundle/jruby/1.9/gems/twitter-5.15.0/lib/twitter/streaming/response.rb:21:in `on_headers_complete'", "org/ruby_http_parser/RubyHttpParser.java:370:in `\<\<'", "/opt/Oracle/relk/logstash/vendor/bundle/jruby/1.9/gems/twitter-5.15.0/lib/twitter/streaming/response.rb:16:in `\<\<'", "/opt/Oracle/relk/logstash/vendor/bundle/jruby/1.9/gems/logstash-input-twitter-2.2.2/lib/logstash/inputs/twitter/patches.rb:31:in `stream'", "/opt/Oracle/relk/logstash/vendor/bundle/jruby/1.9/gems/logstash-input-twitter-2.2.2/lib/logstash/inputs/twitter/patches.rb:58:in `request'", "/opt/Oracle/relk/logstash/vendor/bundle/jruby/1.9/gems/twitter-5.15.0/lib/twitter/streaming/client.rb:37:in `filter'", "/opt/Oracle/relk/logstash/vendor/bundle/jruby/1.9/gems/logstash-input-twitter-2.2.2/lib/logstash/inputs/twitter.rb:128:in `run'", "/opt/Oracle/relk/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.3.4-java/lib/logstash/pipeline.rb:342:in `inputworker'", "/opt/Oracle/relk/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.3.4-java/lib/logstash/pipeline.rb:336:in `start\_input'"], :options=\>nil, :level=\>:warn}
