Arpit Agarwal commented on HADOOP-12897:
----------------------------------------

Minor comment. You can simplify the following code:
{code}
      } catch (IOException ex) {
        throw wrapExceptionWithMessage(ex,
            "Error while authenticating with endpoint: " + url);
      } catch (AuthenticationException ex) {
        throw wrapExceptionWithMessage(ex,
            "Error while authenticating with endpoint: " + url);
      }
{code}
as follows:
{code}
      } catch (IOException | AuthenticationException ex) {
        throw wrapExceptionWithMessage(ex,
            "Error while authenticating with endpoint: " + url);
      }
{code}

> If {{KerberosAuthenticator.authenticate}} can't connect to the endpoint, you get a stack
trace, but without the URL it is trying to talk to.
> That is: it doesn't have any equivalent of the {{NetUtils.wrapException}} handler —which
can't be called here as its not in the {{hadoop-auth}} module
