CDH禁用kerberos

1、zookeeper enableSecurity 设置为false。配置kerberos时候是需要勾选该选项的

2、hbase 设置 hbase.security.authentication 为false

取消勾选 hbase.security.authorizatio

3、hdfs 

设置 hadoop.security.authentication 为simple

取消勾选 hadoop.security.authorization

重置dn address 端口为50010

dfs.datanode.address = 50010

 

重置 dn http端口为 50075

dfs.datanode.http.address 修改为50075

4、hue

Hue实例中删除Kerberos Ticket Renewer

 

5、重启集群前，删除zk 下的/hbase 节点

(1)Zookeeper添加参数(跳过zk目录权限检查): java Configuration Options for Zookeeper Server : 

-Dzookeeper.skipACL=yes 

(2)删除zk元数据目录:hbase zkcli;rmr /hbase  或者直接 zookeeper-client ; rmr /hbase

如果不执行以上操作，将会执行以下错误：

org.apache.zookeeper.KeeperException$NoAuthException: KeeperErrorCode = NoAuth for /hbase/running

抛出以上错误的原因是：

zookeeper和hbase启用kerberos后，/hbase目录权限属于hbase。

getAcl /hbase/table

'world,'anyone

: r

'sasl,'hbase

: cdrwa

网上参考的解决方案:

重新启用kerberos，然后手动将zookeeper中/hbase下所有znode权限设置为world:anyone:cdrwa。

使用hbase账号，然后在hbase zkcli中进行修改。如果启动zkcli时报jline相关错误，只需将zookeeper/lib目录下0.9版本删除，然后拷贝1.1.2版本到此目录即可解决。

---

某并未使用以上方案解决，只用了之上的第一个方案，在zk server中添加跳过ACL检查的代码，然后删除/hbase节点.

 

 

重启集群 ！
