Question

我正在尝试将hadoop与英特尔光泽融为一体。我已将hadoop-lustre-plugin-3.1.0添加到hadoop-2.7.3/lib/native文件夹。 Lustre安装在/mnt/lustre。当我使用start-all.sh

启动hadoop时出现以下错误

[root@master hadoop]# start-all.sh 
This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh
17/04/06 17:36:55 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
Incorrect configuration: namenode address dfs.namenode.servicerpc-address or dfs.namenode.rpc-address is not configured.

core-site.xml：

maprd-site.xml中

<property>
    <name>mapreduce.job.map.output.collector.class</name>
    <value>org.apache.hadoop.mapred.SharedFsPlugins$MapOutputBuffer</value>
</property>
<property>
    <name>mapreduce.job.reduce.shuffle.consumer.plugin.class</name>
    <value>org.apache.hadoop.mapred.SharedFsPlugins$Shuffle</value>
</property>

HDFS-site.xml中

<property>
<name>dfs.name.dir</name>
<value>/mnt/lustre/hadoop/hadoop_tmp/namenode</value>
<description>true</description>
</property>

我是否在配置文件中遗漏了任何配置？

Answer 1

由于fs.defaultFS包含特定于lustre的URI，因此启动脚本无法确定必须启动Namenode的主机。

在hdfs-site.xml，

中添加此属性

<property>
   <name>dfs.namenode.rpc-address</name>
   <value>namenode_host:port</value>
</property>

在为Lustre配置Hadoop时无法启动名称节点
