Chris Nauroth commented on HADOOP-12551:
----------------------------------------
The changes to address the FindBugs warnings look good.
Regarding the multi-threaded testing suggestion, I see the change in
{{testMultiThreadedPageBlobOpenScenario}}, but there are other tests still
using {{while (runCount < maxCount)}}. Sorry if this wasn't clear, but I
actually wanted to suggest making the change consistently across all of these
tests. Could you please revise the patch again? I think that's the last
change we'll need.

> HADOOP-12533 introduced FileNotFoundException to the read and seek API for
> WASB. The open and getFileStatus api currently throws FileNotFoundException
> correctly when the file does not exists when the API is called but does not
> throw the same exception if there is another thread/process deletes the file
> during its execution. This Jira fixes that behavior.
> This jira also re-examines other Azure storage store calls to check for
> BlobNotFoundException in setPermission(), setOwner, rename(), delete(),
> open(), listStatus() APIs.
