Logstash: 1.4  
Elasticsearch: 1.2

When trying the examples of 'Logstash 10-minute Tutorial  
[http://www.logstash.net/docs/1.4.1/tutorials/10-minute-walkthrough/](http://www.logstash.net/docs/1.4.1/tutorials/10-minute-walkthrough/)' step  
3 goes wrong. First, the problem is 'embedded' is not accepted, resulting  
in Java-errors. So I changed the output a little bit:  
output {  
stdout {  
codec =\> rubydebug  
}  
elasticsearch\_http {  
host =\> "localhost"  
}  
}

But now, the errors and warnings keep flushing over my screen, which can  
only be stopped by another shell. What caused the problem, I have no idea.

If I didn't misread, the problem is it failed to create an index.

# bin/logstash agent -f hello-search.conf

Using milestone 2 output plugin 'elasticsearch\_http'. This plugin should be  
stable, but if you see strange behavior, please let us know! For more
