Hi @Jeffery_Yemin,
Thanks for the reply. I looked at the GSSAPIAuthenticator code and the issue is with getHostName method. Currently, getHostName method simply returns the hostname from ServerAddress. If ServerAddress has ability capture gssapiHostname and use that value as hostname if available. That could solve the issue. After doing this change in GSSAPIAuthenticator class, it worked for me but I am not really sure about side effects.
Thanks,
Surendra
