[~cnauroth] Thanks for the review Chris.

I see that inside NativeAzureFileSystem class there are calls to IOUtils.cleanup(LOG, out).
However IOUtils only exposes cleanup API that take Commons Logging objects and not Slf4j objects.


considering that Hadoop community is moving towards use of Slf4j, would the IOUtils be exposing
an Api that that takes Slf4j?

If not, then I looked at the code for cleanup, it basically closes

> Logging around the WASB component is very limited and it is disabled by default. This
improvement is created to add logging around Reads, Writes and Deletes when Azure Storage
Exception to capture the blobs that hit the exception. This information is useful while communicating
