That is an incorrect JAVA_HOME. You should not be pointing it to the
java executable, but rather the root directory:

export JAVA_HOME=/usr/lib/jvm/jdk1.6.0_27

Hello,

This is the following error that I get when I am trying to start hadoop
using start-all.sh

starting namenode, logging to
/var/log/hadoop/root/hadoop-root-namenode-zombie.out
/usr/libexec/../bin/hadoop: line 321: /usr/lib/jvm/java-6-sun/bin/java: No
such file or directory
/usr/libexec/../bin/hadoop: line 387: /usr/lib/jvm/java-6-sun/bin/java: No
such file or directory

Srikanth,

Before you run "start-all.sh", what does "echo $JAVA_HOME" print?

You can also set JAVA_HOME in your conf/hadoop-env.sh to point to the
right Java home directory on your machine. For example, the Oracle JRE
RPMs would install to /usr/java/default.

Can you check what is the JAVA_HOME it displays, when you echo on the same console?
Also try setting JAVA_HOME in hadoop-env.sh. This should unblock your work.
