Hi, hadoop is normally designed to write to disk. There are a special file format, which writes output to RAM instead of disk. But I don't have an idea if it's what you're looking for. If what you said exists, there should be a mechanism which sends output as objects rather than file content across computers, as far as I know there is no such feature yet.
Good luck. 2009/4/2 andy2005cst <[email protected]> > > I need to use the output of the reduce, but I don't know how to do. > use the wordcount program as an example if i want to collect the wordcount > into a hashtable for further use, how can i do? > the example just show how to let the result onto disk. > myemail is : [email protected] > looking forward your help. thanks a lot. > -- > View this message in context: > http://www.nabble.com/HELP%3A-I-wanna-store-the-output-value-into-a-list-not-write-to-the-disk-tp22844277p22844277.html > Sent from the Hadoop core-user mailing list archive at Nabble.com. > > -- M.
