Description

Kudu Java client doesn't retain the original hostname and replaces them with the resolved IPAddress in the kerberos principal. This results in error such as following:

         error Message is Server not found in Kerberos database

KrbException: Server not found in Kerberos database (7) - LOOKING_UP_SERVER 

 aserbin suggested this might require the fix done on cpp client side in KUDU-2032 to be extended to Java client also.
