华为认证-- sun.security.krb5.KrbException: Server not found in Kerberos database (7)

一、问题描述
在用华为安全模式接入kafka时，一直提示错误：

javax.security.sasl.SaslException: An error: (java.security.PrivilegedActionException: javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Server not found in Kerberos database (7) - UNKNOWN_SERVER)]) occurred when evaluating SASL token received from the Kafka Broker. This may be caused by Java's being unable to resolve the Kafka Broker's hostname correctly. You may want to try to adding '-Dsun.net.spi.nameservice.provider.1=dns,sun' to your client's JVMFLAGS environment. Users must configure FQDN of kafka brokers when authenticating using SASL and `socketChannel.socket().getInetAddress().getHostName()` must match the hostname in `principal/hostname@realm` Kafka Client will go to AUTH_FAILED state.

Caused by: sun.security.krb5.KrbException: Server not found in Kerberos database (7) - UNKNOWN_SERVER
