2) SSL

22 ssh

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

Miscellaneous:

10000 Spark SQL Thrift server port. Only in enabled

1024 - 65355 JMX reconnection / loopback ports

For Unrestricted access to Analytics nodes:

1) spark port for the driver to listen on &

2) Spark port for all block managers to listen on. 

we might require ports 11000 to 11032 as both takes default of 16 port max retries constituting a total of 32 ports.

Here, either we might use the ports that were not used by the organization if not 11000.
