> HBase relies on FileSystems implementing CanUnbuffer.unbuffer() to force input streams
to free up remote connections (HBASE-9393Link). This works for HDFS, but not elsewhere.
> WASB {{BlockBlobInputStream}} can implement this by closing the stream 
>  in ({{closeBlobInputStream}}, so it will be re-opened elsewhere.
