Subject RE: Hadoop 2.6.0 Error
Date Wed, 25 Mar 2015 06:52:48 GMT
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.

Thanks & Regards

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

Regards,
