Chris Nauroth commented on HADOOP-12533:
----------------------------------------

bq. This is hitting a bit of deadline for a release...

This patch currently is targeted to Apache Hadoop 2.8.0, which does not yet have any proposed
release timeline.  That said, I do expect we can finish this out today and commit.

> Currently WASB throws a IOException in read and seek API for both Block and Page blobs
for scenarios where the backing blobs do not exists. This creates problems for applications
like HBase which expect a FileNotFoundException in these scenarios. 
> The fix for the problem is to check if the exceptions from Azure storage is because for
Blob not found and throw FileNotFound exception if that is the case.
