报错信息：

[[email protected] qun]# hdfs dfs -ls /
19/05/29 18:06:15 WARN ipc.Client: Exception encountered while connecting to the server : org.apache.hadoop.security.AccessControlException: Client cannot authenticate via:[TOKEN, KERBEROS]
ls: Failed on local exception: java.io.IOException: org.apache.hadoop.security.AccessControlException: Client cannot authenticate via:[TOKEN, KERBEROS]; Host Details : local host is: "hadoop001/172.17.239.230"; destination host is: "hadoop001":8020;

解决办法:将krb5.conf文件中的default_ccache_name注释掉，然后执行kdestroy,重新kinit，问题解决

[libdefaults]
dns_lookup_realm = false
ticket_lifetime = 24h
renew_lifetime = 7d
forwardable = true
rdns = false
default_realm = HADOOP.COM
#default_ccache_name = KEYRING:persistent:%{uid}
