Thank you for your quick reply!! I cannot change the hadoop conf files because they are owned by a person who has left the company, though I have the root access. My Java version is java version "1.5.0_07" Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_07-b03) Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_07-b03, mixed mode)
