<div class="">Hi all,
I have two distributed applications running on
two different nodes. And from one node I tried
to call the function on the remote node by doing
RPC, and its been observed that all the debug
prints given in the application running on the
remote node is getting printed on the host
node's console.
Can somebody please tell me in detail why this
is happening and how the RPC in erlang works. ?
Thanks in advance.
Arun P.
