---------------------------------

             Summary: java.net.PortUnreachableException: null when using DatagramChannelSender (UDP)
                 Key: NIFI-6414
                 URL: https://issues.apache.org/jira/browse/NIFI-6414
             Project: Apache NiFi
          Issue Type: Bug
          Components: Extensions
    Affects Versions: 1.9.2
         Environment: CentOS 7 with NiFi 1.9.2
            Reporter: Sol Huebner


I get "java.net.PortUnreachableException: null" when I use PutSyslog using UDP. I have no issues with TCP. The issue only occurs when you try to use the connection multiple times.

I found a similar issue here: [http://www.java-gaming.org/index.php?PHPSESSID=u7ufav5hekdirj9991jll36e81&topic=1751.msg16721#msg16721]


So I tried to modify DatagramChannelSender.java of the nifi-processor-utils:

if (!channel.isConnected()) {
{color:#59afe1}channel.socket().bind(newInetSocketAddress(InetAddress.getByName(host), port));{color}
channel.connect(newInetSocketAddress(InetAddress.getByName(host), port));
}
 
And with the added line I have no more issues and it compiled without errors.
