Invalid cache specification

I'm having some trouble using caching in my pig script.

Lets say I have a file in `/home/user/file.dat`. When I try to reference 
it with cache('/home/user/file.dat') I get the following error:

Invalid cache specification: '/home/user/file.dat' does not exist. What 
am I missing here?

Thanks,

Shane

Shane,

Are you running Cloudera's Distribution?  I ran into a bug where it wasn't
actually copying the files to the datanodes.  I had to manually copy the
file to each datanode.
