Thanks for the response, Joe. in the non-working setup, kafka user had all the permissions for its own directories and log files. I ran normal tests via the command line, as user "kafka" and all worked.
I think my question is: is there any non-AF_INET socket communication between kafka clients and servers ? something like shared memory, or (god forbid) same files access !?
