修改配置

首先需要jdk1.7

[[email protected] jdk1.7.0_80]# echo $JAVA_HOME
/usr/java/jdk1.7.0_80

修改 etc/hadoop/hadoop-env.sh 文件

在hadoop-env.sh文件中修改java_home
export JAVA_HOME=/usr/java/jdk1.7.0_80

增加HADOOP_PREFIX
export HADOOP_PREFIX=/home/hadoop/app/hadoop-2.6.0-cdh5.7.0

修改etc/hadoop/core-site.xml:

<configuration>
    <property>
        <name>fs.defaultFS</name>
        <value>hdfs://hadoop:9000</value>
    </property>
</configuration>

修改etc/hadoop/hdfs-site.xml:

配置ssh免密

删除.ssh文件夹 防止冲突
# rm -rf .ssh

生成ssh秘钥

# cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

修改authorized_keys 文件权限
chmod 600 authorized_keys
