> 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
