Specifying config file for API node

[Anand Sriraman]

Hi,
I want to know how to specify the config file for the mysqld process other
than my.cnf. I've tried

mysqld --defaults-file=<path>

but by doing this my API node isn't showing up as connected in the
management server when i try show command.

This is related to my earlier query on setting up both API and data node on
the same machine.

Thanks in advance.
