how to set the conf in pig to use a cached file.

[Kochis, Allan]

Hi
 
I would like to distribute cache a file of key value pairs. 
Mridul pointed that to do this set
 
mapred.cached.archives=hdfs://host:port/mypath/file#link
mapred.create.symlink=yes
 
My question is how do I set these in pig?
 
 
Thanks,
 
Allan
