I am slow, you already answered yourself. Hi, Yes. If you look in the log on the Riak node you well see that the env around your Fun is the module that contains it (even though it is an anon fun, this is weird to a JavaScript programer) so if the module changes you will need to reload it on the riak nodes. If you need highly dynamic, oft changing M/R fun it might be best to use JavaScript. If it is just because you are in dev then use that gist to propagate your code changes (maybe hook it into a reloader type module (http://code.google.com/p/mochiweb/source/browse/trunk/src/reloader.erl)).
There is a thread about this on the trapexit forum here http://www.trapexit.org/forum/viewtopic.php?p=53520 Cheers Russell On 22 Apr 2010, at 19:35, Abeming Sf wrote: > Hi Russel, > > Thank you for the link. > > After recompile mapred module, do we need to add it again to riak node?I > still got the same error "all nodes failed" when execute m/r from that module. > > Regards, > Abe > > On 23 April 2010 01:45, Russell Brown <[email protected]> wrote: > Hi, > Have a look at this thread > > http://lists.basho.com/pipermail/riak-users_lists.basho.com/2010-April/000830.html > > The issue is that the code needs to be on the riak node.
