My elasticsearch cluster contains two nodes: node\_ip1,node\_ip2.  
When I used logstash-output-elasticsearch to connect elasticsearch cluster, there were lots of tcp time\_wait between logstash and elasticsearch nodes. Here is my logstash configuration:

output {  
elasticsearch {  
hosts =\> ["http://node\_ip1:9200"]  
manage\_template =\> true  
index =\> "logstash-%{+YYY.MM.dd}"  
flush\_size =\> 1500  
idle\_flush\_time =\> 10  
workers =\> 4  
codec =\> "json"  
}  
}

As above, logstash agent had connected to node\_ip1:9200, but there were lots of tcp time\_wait between logstash agent and node\_ip2:9200 (Another elasticsearch node).

How do I resolve this problem?

Is it causing a problem?

In my situation, it really occupies network resources.
