Key: PIG-562
URL: https://issues.apache.org/jira/browse/PIG-562
Project: Pig
Issue Type: Improvement
Components: tools
Affects Versions: types_branch
Reporter: Santhosh Srinivasan
Priority: Minor
Fix For: types_branch
In parameter substitution, the order of processing order is stated as follows:
Processing Order
1. Configuration files are scanned in the order they are specified on the
command line. Within each file, the parameters are processed in the order they
are specified.
2. Command line parameters are scanned in the order they are specified on
the command line.
The order needs to be flipped, allowing the use of command line parameters to
define values for variables declared in parameter files.
