> HADOOP-11693 passes exponential retry policy to Azure storage SDK when Azure storage
throttling happens. However, when I looked at the source code of Azure storage SDK. Storage
exceptions such as throttling exception are non-retryable.
> I would like to add retry in WASB driver instead of depending on Azure storage SDK to
make sure retry happens when Azure storage throttling fires.
