> Azure Storage throttling affects HBase operations such as archiving old
> WALS and others. In such cases the storage driver needs to detect and handle
> the exception. We put in this logic to do the retries however the condition
> to check for the exception is not always met due to inconsistency in which
> the manner the error code is passed back. Instead the retry logic should
> check for http status code (503) which is more reliable and consistent check
