Hi I currently run hadoop with local option.
Does this mean that still map reduce will work on the local system? If that is so, then hadoop incorporates two things 1)distributed file system 2) map reduce And the distributed file system - is mainly for moving data around between networked computers. Is the above statement true? I have one more question. With the local option set, Is there the concept of a jobtracker and a tasktracker? Does the same machine act as both of the above or is it only a map reduce implementation. The problem is i am trying to grasp the two things separately(from code point of view) and they are intercoupled to a great extent. Rgds Prabhu
