Subject Estimating Hadoop temporary file storage space
Date Mon, 25 Aug 2008 20:46:39 GMT
Hi all,

Is there a formula one can use to determine the amount of temporary
file storage that Hadoop uses for its map-reduce, if we know the size
of the input files?  Assuming that the mapper and reducer's output the
same amount of data as the input?
