我们已经学习了
Kerberos

Kerberos
、
HDFS/Hive
和
Hive
连接器的组合使用。
默认情况下，
Hive
连接器没有启用认证，但该连接器支持

认证。你需要做的
就是将连接器配置为与
Hadoop
集群上的两个服务一起工作：
• The Hive Metastore Service
（
Hive
元存储服务）
• The Hadoop Distributed File System(Hadoop
分布式文件系统）
如果你的
krb5.conf
不在
/etc/krb5.conf
内，则必须使用
jvm.config
文件中的
java.security.krb5.conf
这一
JVM
属性显式地进行设置：
-Djava.security.krb5.conf=/example/path/krb5.conf

可以在
catalog

HMS
启用
Kerberos
认证：
hive.metastore.authentication.type=KERBEROS
hive.metastore.service.principal=hive/hive-metastore-host.example.com@EXAMPLE.COM ...
