2015-10-08 22:46:15,211 WARN [main-SendThread(xxxxxxx)] client.ZooKeeperSaslClient: Could not login: the client is being asked for a password, but the Zookeeper client code does not currently support obtaining a password from the user. Make sure that the client is configured to use a ticket cache (using the JAAS configuration setting 'useTicketCache=true)' and restart the client. If you still get this message after that, the TGT in the ticket cache has expired and must be manually refreshed. To do so, first determine if you are using a password or a keytab. If the former, run kinit in a Unix shell in the environment of the user who is running this Zookeeper client using the command 'kinit <princ>' (where <princ> is the name of the client's Kerberos principal). If the latter, do 'kinit -k -t <keytab> <princ>' (where <princ> is the name of the Kerberos principal, and <keytab> is the location of the keytab file). After manually refreshing your cache, restart this client. If you continue to see this message after manually refreshing your cache, ensure that your KDC host's clock is in sync with this host's clock.

2015-10-08 22:46:15211警告[main SendThread（xxxxxxx）]客户端。ZooKeeperSaslClient:无法登录：客户端需要密码，但Zookeeper客户端代码当前不支持从用户处获取密码。确保客户端配置为使用票证缓存（使用JAAS配置设置“useTicketCache=true”），然后重新启动客户端。如果在此之后仍收到此消息，则票证缓存中的TGT已过期，必须手动刷新。为此，首先确定您使用的是密码还是键盘。如果是前者，请在运行Zookeeper客户端的用户的环境中，在Unix shell中使用命令“kinit”（其中是客户端的Kerberos主体的名称）运行kinit。如果是后者，则执行'kinit-k-t'（其中是Kerberos主体的名称，是keytab文件的位置）。手动刷新缓存后，重新启动此客户端。如果手动刷新缓存后仍看到此消息，请确保KDC主机的时钟与此主机的时钟同步。
