----------------------------------------------
Hi Alejandro, [~bowenzhangusa] is working on it. I tried to change
TestKerberosAuthenticator but it was not able to reproduce the problem.
> KerberosAuthenticator failed to fall back to PseudoAuthenticator after
> HADOOP-10078

> Key: HADOOP-10398

> {code}
> //KerberosAuthenticator.java
> if (conn.getResponseCode() == HttpURLConnection.HTTP_OK) {
> LOG.debug("JDK performed authentication on our behalf.");
> // If the JDK already did the SPNEGO back-and-forth for
> // us, just pull out the token.
> AuthenticatedURL.extractToken(conn, token);
> return;
> } else ...
> {code}
> The problem of the code above is that HTTP_OK does not implies authentication
> completed. We should check if the token can be extracted successfully.
