> Before [HADOOP-13556], Configuration.getPropsWithPrefix() used the Configuration.get()
method to get the value of the variables.   After [HADOOP-13556], it now uses props.getProperty().
> The difference is that Configuration.get() does deprecation handling and more importantly
variable substitution on the value.  So if a property has a variable specified with ${variable_name},
it will no longer be expanded when retrieved via getPropsWithPrefix().
> Was this change in behavior intentional?  I am using this function in the fix for [MAPREDUCE-7069],
but we do want variable expansion to happen.
