I am establishing on an Amazon cluster the said module and basing my attempt on the literature in http://search.cpan.org/~spazm/Hadoop-Streaming-0.110030/lib/Hadoop/Streaming.pm specifically

This question is based on 

      
   local::lib
    * install all modules into a local::lib controlled directory, push
+ this directory to all of the hadoop cluster boxes (rsync, app instal
+ler, nfs mount ), explicitly include this directory in a use lib or u
+se local::lib line in        your mapper/reducer/combiner files.

[download]

My objective is simple. Install all modules into a local::lib.

Tar up the directory and use a bootstrap script to copy over to each data node on Elastic Map Reduce ( amazon ) cluster.

Untar and use the use lib or use local::lib to use these modules in my Mapper/Reducer etc.

What I am against is that when I untar and try using the modules, I have an unsattified link error

Can't locate loadable object for module Sub::Name in @INC...

I can get to the pm file but a shared object needed by Name.pm is missing.

This of of course points to a missing shared object and is pbly b’coz of the fact that I copied the local::lib controlled directory, rather than installing as one would normally do if working standalone.

I was wondering how did you folks get this to work. ( You guys obviously have this working as else that would not be one of the alternatives you suggested )
