Filebeat load balance problem

I try to set up filebeat to send log file to 2 logstash instances using load balance with this
hosts: ["host1:5044","host2:5044"]
loadbalance: true

but filebeat always send logs to hosts1 even after I stop the logstash service on hosts1, it still try to connect to hosts1


What version are you running?

I am using 1.0.1
