黑猴子的家：Hadoop 修改本地临时文件存储目录

1、停止进程，按照顺序停止

[victor@node1 hadoop-2.8.2]$ sbin/yarn-daemon.sh stop nodemanager
[victor@node1 hadoop-2.8.2]$ sbin/yarn-daemon.sh stop resourcemanager
[victor@node1 hadoop-2.8.2]$ sbin/hadoop-daemon.sh stop datanode
[victor@node1 hadoop-2.8.2]$ sbin/hadoop-daemon.sh stop namenode

2、修改core-site.xml

<!-- 指定hadoop运行时产生文件的存储目录 -->
<property>
        <name>hadoop.tmp.dir</name>
        <value>/opt/module/hadoop-2.8.2/data/tmp</value>
</property>

3、将/opt/module/hadoop-2.8.2路径中的logs文件夹删除掉

[victor@node1 hadoop-2.8.2]$ rm -rf logs/

4、进入到tmp目录将tmp目录中hadoop-victor目录删除掉

[victor@node1 tmp]$ rm -rf hadoop-victor/

5、格式化NameNode

[victor@node1 hadoop-2.8.2]$ hadoop namenode -format

6、启动所有进程

[victor@node1 hadoop-2.8.2]$ sbin/hadoop-daemon.sh start namenode
[victor@node1 hadoop-2.8.2]$ sbin/hadoop-daemon.sh start datanode
[victor@node1 hadoop-2.8.2]$ sbin/yarn-daemon.sh start resourcemanager
[victor@node1 hadoop-2.8.2]$ sbin/yarn-daemon.sh start nodemanager
注：查看/opt/module/hadoop-2.8.2/data/tmp 目录下文件
