Kerberos的| Cloudera的| KrbException：加密类型AES256 C

我一直在试图建立Kerberos进行CDH 4.5这是设置使用的Cloudera Manager安装。

该指令是从以下链接： http://www.cloudera.com/content/cloudera-content/cloudera-docs/CM4Ent/4.5.2/Configuring-Hadoop-Security-with-Cloudera-Manager/cmeechs_topic_4.html

建立和KDC后，我6个文件复制JCE策略的Java到以下位置：/usr/java/jdk1.6.0_31/lib/security/

以下是我的“/var/kerberos/krb5kdc/kdc.conf”文件：

[kdcdefaults]
 kdc_ports = 88
 kdc_tcp_ports = 88

[realms]
 MYREALM.COM = {
  master_key_type = aes256-cts
  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
 }

以下是我的“的/etc/krb5.conf”文件：

[logging]
 default = FILE:/var/log/krb5libs.log
 kdc = FILE:/var/log/krb5kdc.log
 admin_server = FILE:/var/log/kadmind.log

[libdefaults]
 default_realm = MYREALM.COM
 dns_lookup_realm = false
 dns_lookup_kdc = false
 ticket_lifetime = 24h
 renew_lifetime = 7d
 forwardable = true

[realms]
 MYREALM.COM = {
  kdc = node1.hcluster
  admin_server = node1.hcluster
 }

[domain_realm]
 .hcluster = MYREALM.COM
 hcluster = MYREALM.COM

这个文件是存在于所有的节点。

然而，从以下的所有服务无法相互沟通的说明中的所有步骤后。以下是从名称节点日志中的异常：

任何帮助非常感谢。

我能够从Cloudera的得到一些帮助，并计算出该错误是在为JCE策略罐的位置。

正确的位置是：/usr/java/jdk1.6.0_31/jre/lib/security/。
