当前集群

主机名称	IP地址	角色	统一安装目录	统一安装用户
sht-sgmhadoopnn-01	172.16.101.55	namenode,resourcemanager	/usr/local/hadoop(软连接) /usr/local/hadoop-2.7.4 /usr/local/zookeeper（软连接） /usr/local/zookeeper-3.4.9	root
sht-sgmhadoopnn-02	172.16.101.56	namenode,resourcemanager
sht-sgmhadoopdn-01	172.16.101.58	datanode,nodemanager,journalnode,zookeeper
sht-sgmhadoopdn-02	172.16.101.59	datanode,nodemanager,journalnode,zookeeper
sht-sgmhadoopdn-03	172.16.101.60	datanode,nodemanager,journalnode,zookeeper
sht-sgmhadoopdn-04	172.16.101.66	datanode,nodemanager

因sht-sgmhadoopdn-04节点异常，需要从当前集群剔除

1. 在active节点sht-sgmhadoopnn-01修改配置文件

slaves

sht-sgmhadoopdn-

sht-sgmhadoopdn-

sht-sgmhadoopdn-

hdfs-site.xml

  <property>

        <name>dfs.replication</name>

        <value>3</value>

  </property>

hdfs-site.xml

  <property>

        <name>dfs.hosts</name>

        <value>/usr/local/hadoop/etc/hadoop/hdfs_includes</value>

  </property>

  <property>

        <name>dfs.hosts.exclude</name>

        <value>/usr/local/hadoop/etc/hadoop/hdfs_excludes</value>

  </property>

yarn-site.xml

  <property>

        <name>dfs.hosts</name>

        <value>/usr/local/hadoop/etc/hadoop/yarn_includes</value>

  </property>

  <property>

        <name>dfs.hosts.exclude</name>

        <value>/usr/local/hadoop/etc/hadoop/yarn_excludes</value>

  </property>

如果存在上述hosts配置，则可以直接进入第二步，否则，需要将上述参数添加至对应文件里，并重启hdfs和yarn集群

2. 添加白名单和黑名单

白名单

# echo sht-sgmhadoopdn- > /usr/local/hadoop/etc/hadoop/hdfs_includes

# echo sht-sgmhadoopdn- > /usr/local/hadoop/etc/hadoop/hdfs_includes

# echo sht-sgmhadoopdn- > /usr/local/hadoop/etc/hadoop/hdfs_includes

黑名单

# echo sht-sgmhadoopdn- > /usr/local/hadoop/etc/hadoop/hdfs_excludes

# echo sht-sgmhadoopdn- > /usr/local/hadoop/etc/hadoop/yarn_excludes

在所有节点更新上述参数

3. 在active节点sht-sgmhadoopnn-01刷新节点信息

此命令告诉resourcemanager重新读取配置文件yarn-site.xml，将存在yarn_excludes文件中的节点退出当前yarn集群，并不在分配job到该节点

# yarn rmadmin -refreshNodes

输出log
