Below is my conf list, mapreduce jobs are working as expected Server [root@xeon narayana]# cat /var/kerberos/krb5kdc/kdc.conf [kdcdefaults] kdc_ports = 88 kdc_tcp_ports = 88 [realms] NARAYANA.LOCAL = { #master_key_type = aes256-cts # Narayana added max_renewable_life = 7d 0h 0m 0s acl_file = /var/kerberos/krb5kdc/kadm5.acl dict_file = /usr/share/dict/words admin_keytab = /var/kerberos/krb5kdc/kadm5.keytab supported_enctypes = aes256-cts:normal aes128-cts:normal des3-hmac-sha1:normal arcfour-hmac:normal des-hmac-sha1:normal des-cbc-md5:normal des-cbc-crc:normal # Narayana added default_principal_flags = +renewable } clients --------- [cloudera@cloudera-cdh05 hue]$ klist Ticket cache: FILE:/tmp/krb5cc_500 Default principal: cloudera/cloudera-cdh05.narayana.local@NARAYANA.LOCAL Valid starting Expires Service principal 08/19/14 09:48:35 08/20/14 09:48:33 krbtgt/NARAYANA.LOCAL@NARAYANA.LOCAL renew until 08/19/14 09:48:35 [cloudera@cloudera-cdh05 hue]$ cat /etc/krb5.conf [logging] default = FILE:/var/log/krb5libs.log kdc = FILE:/var/log/krb5kdc.log admin_server = FILE:/var/log/kadmind.log [libdefaults] default_realm = NARAYANA.LOCAL dns_lookup_realm = false dns_lookup_kdc = false ticket_lifetime = 24h renew_lifetime = 7d forwardable = true #udp_preference_limit = 1 [realms] NARAYANA.LOCAL = { kdc = 192.168.1.10 admin_server = 192.168.1.10 default_domain = narayana.local } [domain_realm] .narayana.local = NARAYANA.LOCAL narayana.local = NARAYANA.LOCAL [root@cloudera-cdh06 ~]# cat /etc/krb5.conf [logging] default = FILE:/var/log/krb5libs.log kdc = FILE:/var/log/krb5kdc.log admin_server = FILE:/var/log/kadmind.log [libdefaults] default_realm = NARAYANA.LOCAL dns_lookup_realm = false dns_lookup_kdc = false ticket_lifetime = 24h renew_lifetime = 7d forwardable = true #udp_preference_limit = 1 [realms] NARAYANA.LOCAL = { kdc = 192.168.1.10 admin_server = 192.168.1.10 default_domain = narayana.local } [domain_realm] .narayana.local = NARAYANA.LOCAL narayana.local = NARAYANA.LOCAL
