Hi,
I used ambari 2.1.2 to deploy security HDFS, but failed in step of Test
Kerberos Client. I checked ambari server log, and found the following error
info:
```

I followed this guide
http://www.teckstory.com/hadoop-ecosystem/hadoop-kerberos-cluster-setup/ to
do setup. Test KDC Connection works fine. In the page of Provide
information of KDC Admin, I used the principal root/admin@bigdata. I also
manually executed the command "/usr/bin/kadmin -s hd17.bigdata -p
root/admin@BIGDATA -w admin -r BIGDATA -q "get_principal root/admin@BIGDATA"
successfully.
My krb5.conf is as below:
```
[libdefaults]
renew_lifetime = 7d
forwardable = true
default_realm = BIGDATA
ticket_lifetime = 24h
dns_lookup_realm = false
dns_lookup_kdc = false
#default_tgs_enctypes = aes des3-cbc-sha1 rc4 des-cbc-md5
#default_tkt_enctypes = aes des3-cbc-sha1 rc4 des-cbc-md5
[logging]
default = FILE:/var/log/krb5kdc.log
admin_server = FILE:/var/log/kadmind.log
kdc = FILE:/var/log/krb5kdc.log
[realms]
BIGDATA = {
admin_server = hd17.bigdata
kdc = hd17.bigdata
}
```
Could you please help point it out why it fails? Thanks in advance.
Thanks,
Zhenglin
