1.通过hive用户访问
切换用户为hive
[root@slave conf]# su - hive
上一次登录：五 4月 12 13:59:19 CST 2019pts/1 上
[hive@slave ~]$
命令行直接输入hive就可以进入hive
[hive@slave ~]$ hive
log4j:WARN No such property [maxFileSize] in org.apache.log4j.DailyRollingFileAppender.Logging initialized using configuration in file:/etc/hive/2.6.5.0-292/0/hive-log4j.properties
hive>
2.其他用户访问hive
其他用户为授权访问hive会出现以下问题

查看该用户是否有kerberos 凭证
[root@slave conf]# su - nifi
上一次登录：三 4月 3 17:32:05 CST 2019pts/0 上
[nifi@slave ~]$ klist
klist: No credentials cache found (filename: /tmp/krb5cc_996)
[nifi@slave ~]$
如果没有看到有效的凭证，执行如下命令。/etc/security/keytabs/hive.service.keytab为hive kerberos文件
[nifi@slave ~]$ klist -kte /etc/security/keytabs/hive.service.keytab
Keytab name: FILE:/etc/security/keytabs/hive.service.keytab

[nifi@slave ~]$
执行后就可以在该用户下执行kinit。
# 验证用户是否可以从keytab文件登录：
[nifi@slave ~]$ kinit -kt /etc/security/keytabs/hive.service.keytab hive/slave.hdp193.com@EXAMPLE.COM
# 查看有效的凭证
[nifi@slave ~]$ klist

在该用户下执行hive即可进入hive命令界面
