Subject Re: Hadoop 2.6.0 Error

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

Dear Mr. Bhrama Reddy:
Should I type
SET JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-amd64

in root (profile) or at user level (.profile). Reply most welcome

of exporting the JAVA_HOME, Please set JAVA_HOME in system level ( like putting in /etc/profile...)
