不正确的配置:namenode地址dfs.namenode.rpc-address未配置 [英] Incorrect configuration: namenode address dfs.namenode.rpc-address is not configured
问题描述
当我尝试启动DataNode时,出现此错误。从我读过的内容来看,RPC参数只用于HA配置,我没有设置(我认为)。
2014-05-18 18:05:00,589 INFO [main] impl.MetricsSystemImpl(MetricsSystemImpl.java:shutdown(572)) - DataNode指标系统关闭完成。
2014-05-18 18:05:00,589 INFO [main] datanode.DataNode(DataNode.java:shutdown(1313)) - 关闭完成。
2014-05-18 18:05:00,614 FATAL [main] datanode.DataNode(DataNode.java:secureMain(1989)) - secureMain中的异常
java.io.IOException:不正确的配置:namenode地址没有配置dfs.namenode.servicerpc-address或dfs.namenode.rpc-address。

我的文件如下所示:
[root @ datanode1 conf.cluster]#cat core-site.xml
<?xml version ?= 1.0 >
<?xml-stylesheet type =text / xslhref =configuration.xsl?>
<配置>
<属性>
<名称> fs.defaultFS< / name>
< value> hdfs:// namenode:8020< / value>
< / property>
< / configuration>
cat hdfs-site.xml
<?xml version =1.0?>
<?xml-stylesheet type =text / xslhref =configuration.xsl?>
<配置>
<属性>
< name> dfs.datanode.data.dir< / name>
< value> / hdfs / data< / value>
< / property>
<属性>
<名称> dfs.permissions.superusergroup< /名称>
<值> hadoop< /值>
< / property>
< / configuration>
我使用的是最新的CDH5发行版。
安装的软件包
名称:hadoop-hdfs-datanode
Arch:x86_64
版本:2.3.0 + cdh5.0.1 + 567
版本:1.cdh5.0.1.p0.46.el6
有关如何过去这个?
编辑:只需使用Cloudera管理器。
也面临着同样的问题,最后发现fs.default.name值中有一个空格。截断解决问题的空间。上面的core-site.xml似乎没有空间,所以这个问题可能与我的不同。我的2美分
I am getting this error when I try and boot up a DataNode. From what I have read, the RPC paramters are only used for a HA configuration, which I am not setting up (I think).

My files look like:
[root@datanode1 conf.cluster]# cat core-site.xml

</configuration>
I am using the latest CDH5 distro.
Installed Packages
Name : hadoop-hdfs-datanode
Arch : x86_64
Version : 2.3.0+cdh5.0.1+567
Release : 1.cdh5.0.1.p0.46.el6
Any helpful advice on how to get past this?
EDIT: Just use Cloudera manager.
I too was facing the same issue and finally found that there was a space in fs.default.name value. truncating the space fixed the issue. The above core-site.xml doesn't seem to have space so the issue may be different from what i had. my 2 cents
