Question

我使用这个tutorial在带有Java 1.8.0_72的Centos 6.7上安装Hadoop 2.6，在从Hadoop-home / sbin / srart-dfs.sh执行start-dfs.sh之前一切顺利。以下是输出：

[hadoop@10 sbin]$  start-dfs.sh
16/02/26 21:47:40 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

/ etv / bashrc @ line 65似乎有问题。但是，我查了一下，没有修改过。

我使用Mac的并行VM管理器运行CentOS 6.7最终版本，这是一台64位计算机。

提前致谢

编辑您的core-site.xml并添加此部分：

<property>
  <name>hadoop.tmp.dir</name>
  <value>/app/hadoop/tmp</value>
  <description>A base for other temporary directories.</description>
</property>

然后相应地创建文件夹，示例命令：

mkdir -p /app/hadoop/tmp

chown yourHadoopUsername:yourHadoopGroupName /app/hadoop/tmp

chmod 777 /app/hadoop/tmp

格式化您的datanode：

hdfs namenode -format

启动你的hadoop：

start-dfs.sh
start-yarn.sh

Centos 6.7上的Hadoop 2.6 start-dfs.sh错误
