Da Zhou updated HADOOP-15809:
-----------------------------
Description:
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. And that IOException will be caught by AbfsRestOperation,
which will keeps on retrying.
was:Currently getAccessToken throws only IOException and it is never checked
for cases like 401, 403, which lead to unnecessary retry, this should be fixed.
> ABFS: better exception handling when making getAccessToken call
