dolphinscheduler配置kerberos時，出錯，bug如下：

這個說明是kerberos認證失敗，意味著是權限的問題
去查看了秘鑰的權限：

[root@hadoop102 security]# cd keytab/
[root@hadoop102 keytab]# ll
total 48
-rw-rw---- 1 root hadoop 1682 Jun 16 10:15 dn.service.keytab
-rw------- 1 root hadoop  554 Jun 19 11:59 hdfs.keytab
-rw-rw---- 1 root hadoop 1154 Jun 21 09:26 hive.service.keytab
-rw-rw---- 1 root hadoop 1706 Jun 16 10:15 jhs.service.keytab
-rw-rw---- 1 root hadoop 3426 Jun 16 10:15 jn.service.keytab
-rw-rw---- 1 root hadoop 2246 Jun 17 14:14 keystore
-rw-rw---- 1 root hadoop 1682 Jun 16 10:15 nm.service.keytab
-rw-rw---- 1 root hadoop 2242 Jun 16 10:15 nn.service.keytab
-rw-rw---- 1 root hadoop 1122 Jun 16 10:15 rm.service.keytab
-rw-r--r-- 1 root hadoop 1834 Jun 17 11:04 rsa_private.key
-rw-rw---- 1 root hadoop 1730 Jun 16 10:15 spnego.service.keytab
-rw-rw---- 1 root hadoop 1234 Jun 16 10:02 zookeeper.keytab

看到這裡就知道問題在哪裡了，我的 hdfs.keytab權限是rw，是因為我之前刪掉了這個文件，再重新創建了，忘記去更改權限了
解決方案：
加個權限就可以了

[root@hadoop102 keytab]# chown -R root:hadoop /etc/security/keytab/
[root@hadoop102 keytab]# chmod 660 /etc/security/keytab/*
[root@hadoop102 keytab]# ll
total 48
-rw-rw---- 1 root hadoop 1682 Jun 16 10:15 dn.service.keytab
-rw-rw---- 1 root hadoop  554 Jun 19 11:59 hdfs.keytab
-rw-rw---- 1 root hadoop 1154 Jun 21 09:26 hive.service.keytab
-rw-rw---- 1 root hadoop 1706 Jun 16 10:15 jhs.service.keytab
-rw-rw---- 1 root hadoop 3426 Jun 16 10:15 jn.service.keytab
-rw-rw---- 1 root hadoop 2246 Jun 17 14:14 keystore
-rw-rw---- 1 root hadoop 1682 Jun 16 10:15 nm.service.keytab
-rw-rw---- 1 root hadoop 2242 Jun 16 10:15 nn.service.keytab
-rw-rw---- 1 root hadoop 1122 Jun 16 10:15 rm.service.keytab
-rw-rw---- 1 root hadoop 1834 Jun 17 11:04 rsa_private.key
-rw-rw---- 1 root hadoop 1730 Jun 16 10:15 spnego.service.keytab
-rw-rw---- 1 root hadoop 1234 Jun 16 10:02 zookeeper.keytab

在重啟dolphinscheduler，成功，拿了兩個例子進行測試
