I'm using Logstash-forwarder to ship log to Logstash version 1:5.4.3-1 on Ubuntu 16.04. The configuration for lumberjack is:  
input {  
lumberjack {  
port =\> 5000  
type =\> "logs"  
ssl\_certificate =\> "/etc/pki/tls/certs/logstash-forwarder.crt"  
ssl\_key =\> "/etc/pki/tls/private/logstash-forwarder.key"  
}  
}

The connection from forwarder to Logstash has been established, but exception from Logstash is thrown as below.

Logstash-forwarder is no longer supported, can you upgrade to filebeat and a newer Logstash?
