Hi,
The file system object will contain the scheme, authority etc for the given uri
or path. The conf object acts as reference ( unable to get a better terminology
) to this info.
Looking at the MapFileOutputFormat should help provide better understanding as
to how writers and readers are initialized.
Hope this helps,
Amogh

I have a large text file, approximately 500mb containing key value pairs on
each line. I would like to implement Hadoop MapFile so that I can access any
key,value pair fairly quickly. To construct either the Reader or Writer the
MapFile requires a Configurations object and a File System object. I am
confused as to how to create either object, and why they are necessary.
Would someone be so kind to demonstrate to me a trivial example as to how I
can accomplish this.
Thanks in advance.
