hadoop - 为 Lustre 配置 Hadoop 时无法启动名称节点

Question

我正在尝试将 hadoop 与 intel lustre 集成。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

<property>

我在配置文件中是否遗漏了任何配置？

Answer 1

由于 fs.defaultFS 持有 lustre 特定的 URI，启动脚本无法确定必须启动 Namenode 的主机。

在hdfs-site.xml中添加这个属性，

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