hi: the hadoop distributes the data and processing across clusters of commonly available computers.the document said this. but what is the commonly available computers mean? 1U server? or the pc that people daily used on windows? -- View this message in context: http://www.nabble.com/the-question-about-the-common-pc--tp22092022p22092022.html Sent from the Hadoop core-user mailing list archive at Nabble.com.

Re: Re:Re: the question about the common pc?
when i saidpeople daily used on windows,I want to specify the commom handware (not OS)but don't mean hadoop run on windows! I mean that hadoop run on common pc's hardware .certainly linux as OS !

The phrase High Performance Computing equipment makes me think of infiniband, fibre all over the place etc. Hadoop doesn't need that, it runs well on standard pc hardware - i.e. no special hardware you couldn't find in a standard pc. That doesn't mean you should run it on pcs that are being used for other things though. I found that hadoop ran ok on fairly old hardware - a load of old power-pc macs (running linux) churned through some jobs quickly, and I've actually run it on people's office machines during the nights (not on Windows). I did end up having to add an extra switch in for the part of the network that was only 100 mbps to get the throughput though. Of course ideally you would be running it on a rack of 1u servers, but that's still normally standard pc hardware. -- View this message in context: http://www.nabble.com/the-question-about-the-common-pc--tp22092022p22094601.html Sent from the Hadoop core-user mailing list archive at Nabble.com.
question about hadoop and amazon ec2 ?
hi： What is the relationship between the hadoop and the amazon ec2 ? Can hadoop run on the common pc (but not server ) directly ? Why someone says hadoop run on the amazon ec2 ? thanks! -- View this message in context: http://www.nabble.com/question-about-hadoop-and-amazon-ec2---tp22020652p22020652.html Sent from the Hadoop core-user mailing list archive at Nabble.com.
