Subject Three questions about Hadoop
Date Tue, 05 Jan 2010 09:42:08 GMT
Hi team,


When I try to do some research on Hadoop, I have several high level
questions, if any comments from you it will do great help for me:


1. Hadoop assumes the files are big files, but take Google as an example, it
seems the google result for user are small files, so how to understand the
big files?And what’s the file content for example?


2. Why are the files write-once and read-many times?


3. How to install other softwares on Hadoop, is there any special
requirements for the software? Do they need to support the Map/Reduce module
and then can be installed? 


It will be very appreciated for your help.
