Resolution: Invalid
Sorry, but Apache Commons Configurations is a completely different project and has nothing to do with Apache Hadoop.

> The current hadoop config items are mainly interpolated from the *-site.xml files. In our production environment, we need a mechanism that can specify config items through system properties, which is something like the gflags for system built with C++, it's really very handy.
> The main purpose of this patch is to improve the convenience of hadoop systems, especially when people do testing or perf tuning, which always need to modify the *-site.xml files
> If this patch is applied, then people can start hadoop programs in this way: java -cp $class_path -Dhadoop.property.$name=$value $program
