Subject RE: Hadoop 2.6.0 Error

Hello Anand,

 

Set your Java home in hadoop-env.sh - /usr/local/hadoop/etc/hadoop/hadoop-env.sh

 

export JAVA_HOME='/usr/lib/jvm/java-7-openjdk-amd64'

 

It would resolve your error.

 

Thanks,

Subject: RE: Hadoop 2.6.0 Error

 

Hello,

 

I had a similar problem and my solution to this was setting JAVA_HOME in /etc/environment.

 

The problem is, from what I remember, that the start-dfs.sh script calls hadoop-daemons.sh
with the necessary options to start the Hadoop daemons. hadoop-daemons.sh in turn calls hadoop-daemon.sh
with the necessary options via ssh, in an non-interactive fashion. When you are executing
a command via ssh in a non-interactive manner (ex. ssh host1 ‘ls -la’ ) you have a minimal
environment and you do not source the .profile file, and other environment related files.
But the /etc/environment is sourced so you could set JAVA_HOME there. Technically you should
set BASH_ENV there which should point to a file containing the environment variables you need.

http://stackoverflow.com/questions/216202/why-does-an-ssh-remote-command-get-fewer-environment-variables-then-when-run-man,
or man bash

 

Thank you,

Alex

It should be : 

export JAVA_HOME=…

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

Even after setting JAVA_HOME in .profile I get

 

JAVA_HOME is not set and could not be found -error.

 

 

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...)

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
