ubuntu - 已经设置hadoop-env.sh时，如何修复未在Ubuntu上设置的JAVA_HOME？

Question

我已经将hadoop-env.sh设置为:

# export JAVA_HOME=/usr/lib/jvm/java-6-sun

但是当我启动hadoop时仍然有相同的错误:

Warning: $HADOOP_HOME is deprecated.

starting namenode, logging to /usr/local/hadoop/libexec/../logs/hadoop-hduser-namenode dyah-VirtualBox.out
localhost: starting datanode, logging to /usr/local/hadoop/libexec/../logs/hadoop-hduser-datanode-dyah-VirtualBox.out
localhost: Error: JAVA_HOME is not set.
localhost: starting secondarynamenode, logging to /usr/local/hadoop/libexec/../logs/hadoop-hduser-secondarynamenode-dyah-VirtualBox.out
localhost: Error: JAVA_HOME is not set.
starting jobtracker, logging to /usr/local/hadoop/libexec/../logs/hadoop-hduser-jobtracker-dyah-VirtualBox.out
localhost: starting tasktracker, logging to /usr/local/hadoop/libexec/../logs/hadoop-hduser-tasktracker-dyah-VirtualBox.out
localhost: Error: JAVA_HOME is not set.

当我键入 echo $JAVA_HOME时，它显示: /usr/lib/jvm/java-6-sun。
当我键入 java -version时，它显示了Java的版本。

我已经将java的路径导出到 /.bashrc
我不知道这里发生了什么，因为我已经根据教程正确设置了东西。

export语句由前导#注释掉，因此无效。
