Subject: Hadoop 2.6 issue
Dear All:
I am unable to start Hadoop even after setting HADOOP_INSTALL,JAVA_HOME and
JAVA_PATH. Please find below error message
anand_vihar@Latitude-E5540:~/hadoop-2.6.0$ start-dfs.sh --config
/home/anand_vihar/hadoop-2.6.0/conf
Starting namenodes on [localhost]
localhost: Error: JAVA_HOME is not set and could not be found.
cat: /home/anand_vihar/hadoop-2.6.0/conf/slaves: No such file or directory
Starting secondary namenodes [0.0.0.0]
0.0.0.0: Error: JAVA_HOME is not set and could not be found.
anand_vihar@Latitude-E5540:~/hadoop-2.6.0$ echo $JAVA_HOME
/usr/lib/jvm/java-1.7.0-openjdk-amd64
anand_vihar@Latitude-E5540:~/hadoop-2.6.0$ echo $HADOOP_INSTALL

anand_vihar@Latitude-E5540:~/hadoop-2.6.0$
I HAVE MADE NO CHANGES IN HADOOP_ENV.sh and run it succesfully.
