hadoop启动报jvm错
ROO用户下启动hadoop报以下错误：
root@debian:/opt/software/hadoop/hadoop-0.20.205.0/bin# ./start-all.sh

通过在网上查找，有个兄弟是这样处理的：
1.vim hadoop-0.20.205.0/bin/hadoop文件
2.找到如下脚本
if [[ $EUID -eq 0 ]]; then
HADOOP_OPTS="$HADOOP_OPTS -jvm server $HADOOP_DATANODE_OPTS"
else
HADOOP_OPTS="$HADOOP_OPTS -server $HADOOP_DATANODE_OPTS"
fi
把if条件中的改为
HADOOP_OPTS="$HADOOP_OPTS -server $HADOOP_DATANODE_OPTS"
3.然后再启动hadooop，正常启动
