bash: jps: 未找到命令...


java没装好?怎么看装好没有

vi /etc/profile
然后添加了
export JAVA_HOME=/usr/lib/jvm/jdk1.7.0_51

我都是 export PATH 在后面，不知道是不是顺序问题

这是我的core-site.xml 配置，安装的是hadoop2.5.1

不需要加上引号，然后记得文件生效

配置core_site.xml是不是这样写

<configuration>

<property>

<name>fs.default.name</name>

<value>hdfs://localhost:9000</value>

</property>

<property>

<name>dfs.namenode.name.dir</name>

<value>file:/root/usr/hadoop-2.4.0/dfs/name</value>

</property>

<property>

<name>dfs.datanode.data.dir</name>

<value>file:/root/usr/hadoop-2.4.0/dfs/data</value>

</property>

</configuration>

一直提示文档中根元素后面的标记必须格式正确。

不知道什么情况
