Subject Re: Question about mapReduce.
Date Sat, 28 Jan 2012 20:01:18 GMT
So basically if I don't have the data into the  HDFS sistem, the map reduce from HADOOP will
not help me ? 
Because I need  to build a tool that processes big data files, a lot of messages from queues
or databases, 
and I thought that by using the map reduce from HADOOP my life would be easier :)

Thanks for the answers
