> Reporter: Shawn Guo
> Priority: Minor
>
> I add a SocketReceiver test based on the NetworkWordCount.
> Using pipeline and tail the continuous output to netcat
> tail -f xxx.log | nc -lk 9999
> and create a SocketReceiver to receive the continuous output from remote netcat.
> After about 10 hours, SocketReceiver hang and can not receive no more data.
> Netcat only accept one socket connection and push "tail -f xxx.log" to connected socket. other connection is wating in the netcat queue.
> When restart SocketReceive, new socket connection is created to connect to Netcat. However old connection is not closed properly. new connection can not read anything from Netcat.
