Mr. Reddy:
I tried both options, and it does not work. starting daemons fail with
JAVA_HOME not set error. However, if I $ECHO JAVA_HOME it points to the RIGHT
directory. Have you worked on a lower version of Hadoop, I see that on the
website they just have 1.2, 2.5 and 2.6. 1.2 does not have Yarn support. Is 2.5
stable. Path errors are a major issue in hadoop.
Thanks for your suggestions.

HI
Ideally it should take effect , if you configure in .profile or hadoop-env.sh..
As you told that you set in .profile ( hope you did source ~/.profile ),,,
did you verify that take effect..? ( by checking echo $JAVA_HOME,, or
jps..etc )...
Thanks & Regards

JAVA_HOME in system level ( like putting in /etc/profile...)
