[erlang-questions] Cluster Functional test using Slave Nodes

[marcos quesada]

Hi there!

 Sorry about the delay, summertime....

 I've tests *to append or substitute -pa to -pz*, without any positive
results, if i've check which paths are loaded, using: code:get_path().
there's no difference between pa or pz, as a result,still getting the same
error:

   {value,
         {badrpc,
             {'EXIT',
            *     {undef,*
*                     [{cluster,join,[...],...},*
*                      {rpc,'-handle_call_call/6-fun-0-',...}]}}}}]}*

Anyone coould give me any clue?
If i'm not worng, this error is answering that join function is undefined
on cluster module, as you see all those methods are exported, in fact, if
join wasn't exported * cluster_test:cluster_formation() * will ever fail.


-export([start/0, stop/0, join/1, leave/0, status/0, get_ring/0,
get_timestamp/0]).
-export([ping/1, get/1, set/2, register/2]).


Thank you!
