当我尝试从shell启动ubuntu中的hadoop集群时,出现以下错误:

hduser@duleep-G31M-S2L:/usr/local/hadoop$ /usr/local/hadoop/bin/start-all.sh
/usr/local/hadoop/libexec/../conf/hadoop-env.sh: line 9: export: `/usr/lib/jvm/jdk1.7.0_09': not a valid identifier

如果你知道怎么了,请帮忙。

检查你的书的内容 $HADOOP_HOME/conf/hadoop-env.sh 脚本,用于javau home export行-看起来这里有一个尾随引号。
作为参考,我的版本如下:


# The java implementation to use.  Required.

export JAVA_HOME=/usr/lib/jvm/jdk1.7.0_07-i586

如果你仍有问题,请将你的条目粘贴回原来的问题中

nc1teljy

nc1teljy2#

要使用的java实现。
改变这个


# export JAVA_HOME=/usr/lib/jvm/jdk1.5.0

export JAVA_HOME=/usr/lib/jvm/jdk1.6.0
