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

             Summary: bin/solr -e cloud can fail on MacOS
                 Key: SOLR-7635
                 URL: https://issues.apache.org/jira/browse/SOLR-7635
             Project: Solr
          Issue Type: Bug
          Components: scripts and tools
    Affects Versions: 5.2
         Environment: Unix
            Reporter: Upayavira
            Priority: Minor


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)
java      10889 upayavira  118u  IPv6 0xab1d227df2e73ddb      0t0  TCP *:8983 (LISTEN)

}}
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.
