>
> Map tasks involve a number of Contexts -- at least a TaskAttemptContext and a
> MapContext. These context objects contain a Configuration each; when one
> context is initialized, it initializes its own Configuration by deep-copying
> a previous Configuration.
> If one Context instance is used entirely prior to a second, more specific
> Context then the second Context should contain the configuration data
> initialized in the previous Context. This specifically affects the
> interaction between an InputFormat and its RecordReader instance(s).
