> Pig currently ignores parameters from configuration files added statically to Configuration objects as Configuration.addDefaultResource(filename.xml).
> Consider the following scenario -
> In a hadoop FileSystem driver for a non-HDFS filesystem you load properties specific to that FileSystem in a static initializer block in the class that extends org.apache.hadoop.fs.Filesystem for your FileSystem like below - 
> {code}
> class MyFileSystem extends FileSystem {
>         static {
> 		Configuration.addDefaultResource("myfs-default.xml");
> 		Configuration.addDefaultResource("myfs-site.xml");
> 	}
> }
> {code}
> Interfaces like the Hadoop CLI, Hive, Hadoop M/R can find configuration parameters defined in these configuration files as long as they are on the classpath.
> However, Pig cannot find parameters from these files, because it ignores configuration files added statically.
> Pig should allow users to specify if they would like pig to read parameters from resources loaded statically.
