Output logstash not start

Logstash 1.5.1 Elasticsearch 1.4.2

I tried to move from A index aggregated data to B index. but I can't let Logstash output start. here is log message and config file. I don't know what config is wrong.

  Failed to bind to [9300]

This is my logstash config

input {
# Read all documents from Elasticsearch matching the given query
elasticsearch {
hosts => ["192.168.x.x"]
index => "score_log"
type => "keyword_score"
#port => 9200
size => 0
docinfo => true
scan =>  false
query => '{"size":0, "aggs":{"terms_keyword":{"terms".....}'
 }
}
output {
  elasticsearch {
host =>  "192.168.x.x"
cluster => "elasticsearch"
index => "score_temp"
node_name => "Logstash-out"
bind_host => "192.168.x.x"
bind_port => 9300
document_type => "keyword_score"
manage_template => false
}
stdout {codec => rubydebug}
}

Is ES running and listening on 9300?

no on 9200. And Index A an B is on same ES server. I don't know that in this case is valid environment.

Except you are using the node protocol which uses port 9300.

Maybe try switching to HTTP protocol instead.

output 부분을 아래와 같이 한번 해보시면 될 것 같습니다.

output {
elasticsearch {
host => "192.168.x.x"
cluster => "elasticsearch"
index => "score_temp"
node_name => "Logstash-out"
bind_host => "192.168.x.x"
bind_port => 9300
document_type => "keyword_score"
manage_template => false
protocol => "transport"
}

Why are you setting bind_host and bind_port? It seems like Logstash is having problems binding to port 9300, but that's where one would expect ES to be listening.
