Mr. Ravindra: This is visible, however I am unable to modify it, eventhough I have admin priveleges. I am new to the Linux environment. Shall be glad if you did advise. However, as I told you earlier, I have created a batch program which contains, JAVA_HOME setting, HADOOP_INSTALL setting and PATH setting. I have rfun this file but I am still unable to start the daemons. I am following Tom Whyte's -Hadoop definitive Guide book instructions on how to install Hadoop. at $hadoop version works. I am able to format namenode, but fail to start daemons. Reply most welcome.

At a prompt, as su, run the command ‘alternatives - - config java’. Make sure that the oracle version is listed and is marked as the active one.
