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

Brahma Reddy Battula

If anyone of you know of a more stable version please do let me know.

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

Thanks

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

For more details please check the following jira.

Subject: Hadoop 2.6.0 Error

Dear All:

Request help/advise as I am unable to start Hadoop. Performed follow steps in Ubuntu 14.10

1. ssh localhost
2. Did following exports in user defined hadoop.sh and ran it succesfully
    1. EXPORT JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64
    2. EXPORT HADOOP_INSTALL=/home/anand_vihar/hadoop-2.6.0
    3. EXPORT PATH=:$PATH:$HADOOP_INSTALL/sbin:$HADOOP_INSTALL/bin
3. Tested hadoop version succesfully
4. Ran $hadoop namenode -format successfully
5. Modified core-site.xml, hdfs-site.xml and mapred-site.xml to pseudo-distributed mode in
/home/anand_vihar/conf directory
6. Ran $start-dfs.sh --config /home/anand_vihar/conf

Got error JAVA_HOME not set and slaves not found in /conf. If I echo $JAVA_HOME it is pointing
to /usr/lib/jvm/java-7-openjdk-amd6, correctly as set. Help appreciated.

Thanks
