alan wootton commented on HADOOP-196:
-------------------------------------
The constructor:
public Configuration(Configuration other)
sets the defaultResources, and the finalResources but does not use them
because it then sets the properties to a clone of the other.properties.
If someone then calls addFinalResource (as does JobConf) then the
'other' properties are just lost. This becomes a problem if you attempt to use:
public JobConf(Class exampleClass)
My fix (there are several possible ways to fix this) is to just remember
the other.properties and then overlay then whenever getProps() loads the
resources.
