> 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 in
> 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
