> 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.
