Description

On MacOS:

bin/solr -e cloud
said:
Please enter the port for node1 [8983]
Oops! Looks like port 8983 is already being used by another process. Please choose a different port.

Looking at the script, it uses:
PORT_IN_USE=`lsof -Pni:$CLOUD_PORT`
which gave the output:
{{
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
Google 365 upayavira 130u IPv6 0xab1d227df2e5a7db 0t0 TCP [::1]:49889->[::1]:8983 (ESTABLISHED)

}}
This was connections Google Chrome was attempting to make to Solr.

Replacing the above line with this:

PORT_IN_USE=`lsof -Pni:$CLOUD_PORT | grep LISTEN`

resolved the issue. Very simple patch attached.
