#### 关闭zookeeper参数 ```sh enableSecurity (Enable Kerberos Authentication) False (uncheck) ``` #### 关闭hbase参数 ```sh hadoop.security.authentication Simple hadoop.security.authorization False (uncheck) dfs.datanode.address from 1004 (for Kerberos) to 50010 (default) dfs.datanode.http.address from 1006 (for Kerberos) to 50075 (default) Data Directory Permissions from 700 to 755 ``` #### 关闭kafka参数 ```sh kerberos.auth.enable False ``` #### 关闭yarn参数 ```sh yarn.nodemanager.linux-container-executor.nonsecure-mode.local-user yarn yarn.nodemanager.linux-container-executor.nonsecure-mode.limit-users false ``` #### 重启相关服务 #### 问题 `问题一、failure controller服务报code:NOAUTH for path /hadoop-ha/nameservice1/ActiveStandbyElectorLock` 分析:zookeeper查看getAcl /hadoop-ha，failure controller节点无权限访问读取该节点解决方法:添加zookeeper权限检查参数、删除rmr /hadoop-ha,初始化故障转移Znode ```sh 1.添加-Dzookeeper.skipACL=yes配置项(打开zookeeper配置，搜索java关键字) 2.重启zookeeper服务 3.登录zkcli删除zkfc znode:rmr /hadoop-ha/nameservice-test1 4.删除-Dzookeeper.skipACL=yes配置项 5.重启zookeeper及相应服务 6.初始化故障转移Znode ```
