> Currently in *getTokenSingleCall()*: if it get a HTTP failure response, it
> tries to consume inputStream in httpUrlConnection, which will *always* lead
> to an *IOException* and this exception never get checked in
> *AzureADAuthenticator*.
> As a result the httpStatus code is never checked in the retry policy of
> AzureADAuthenticator. Tthat IOException will be caught by AbfsRestOperation,
> which will keep on retrying.
