Review comment:
+1 on this.
also do you think we should keep the `isCredentialsConfigured` API available
for 1 more release and it can simply be:
```
@Deprecated
public static boolean isCredentialsConfigured(UserGroupInformation ugi,
boolean useTicketCache) throws Exception {
return isKerberosSecurityEnabled(ugi) && isKerberosCredentialsValid(ugi,
useTicketCache);
}
```
