Question

Update table_name set date_field=DateAdd(yyyy,2012-year(date_field),date_field)

在上面的代码中，我想开始像

这样的haoop服务

命令抛出错误说

namenode,datanode,secondarynamenode,node manager

所以要解决这个问题我必须做的事情。

我有同样的错误。由于名为core-site.xml的Hadoop配置文件，我收到此错误。您的core-site.xml可能包含以下代码：

<configuration>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:9000 </value>
</property>
</configuration>

由于9000和</value>之间存在空格而发生错误。要克服，请使用以下代码段替换core-site.xml：

<configuration>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:9000</value>
</property>
</configuration>

您必须删除9000 </valve>之间的空格，该空格应与9000</value>类似。

启动namenode和datanode时出错
