> Currently, Pig read the first ever pig.properties in CLASSPATH. Pig has a 
> default pig.properties and if user have a different pig.properties, there 
> will be a conflict since we can only read one. There are couple of ways to 
> solve it:
> 1. Give a command line option for user to pass an additional property file
> 2. Change the name for default pig.properties to pig-default.properties, and 
> user can give a pig.properties to override
> 3. Further, can we consider to use pig-default.xml/pig-site.xml, which seems 
> to be more natural for hadoop community. If so, we shall provide backward 
> compatibility to also read pig.properties, pig-cluster-hadoop-site.xml.
