The quick solution to this is Create *hadoop-env.sh* file in your configuration folder ( same place where you have your hdfs-site.xml etc)
Add the following into it export JAVA_HOME=/home/hadoop/software/java/jdk1.6.0_31 Just change the path above to correct JAVA_HOME Just write back if it doesnt work.
