Kafka使用kerberos加密时如果在机器hosts中写入该机器ip其它的域名在kerberos域名前面时启动kafka报DNS域名解析出问题

hosts配置：
192.168.21.133 www.bnvkd.com
192.168.21.133 test.com
192.168.21.133 kdc
其中192.168.21.133 kdc是kerberos使用的域名
启动kafka时详细报错：

hosts文件是下面这样可以正常启动
192.168.21.133 kdc
192.168.21.133 www.bnvkd.com
192.168.21.133 test.com
如果把把kerberos域名放在上面的两个域名前面可以正常启动，这种有什么方法可以解决。
