Add Entire Files Text as Map Key in Hadoop

I'm looking for a way to loa开发者_StackOverflow中文版d an entire file text into my map. Not a single line at a time like TextInputFormat does.

So that when I do value.toString in my map it gives me the entire input to work with.

You have to put every line into a StringBuilder until you've reached the end of file. Or you override your own RecordReader that provides this functionality. But I would not recommend this.

I would path name of the file to the mapper, and then will be free to load is entirely or do some kind of streaming processing.
