> During HFile create, at the end when called close() on the OutputStream,
> there is some pending data to get flushed. When this flush happens, an
> Exception is thrown back from Storage. The Azure-storage SDK layer will throw
> back IOE. (Even if it is a StorageException thrown from the Storage, the SDK
> converts it to IOE.) But at HBase, we end up getting IllegalArgumentException
> which causes the RS to get aborted. If we get back IOE, the flush will get
> retried instead of aborting RS.
> The reason is this
> NativeAzureFsOutputStream uses Azure-storage SDK's BlobOutputStreamInternal.
> But the BlobOutputStreamInternal is wrapped within a SyncableDataOutputStream
> which is a FilterOutputStream. During the close op, NativeAzureFsOutputStream
> calls close on SyncableDataOutputStream and it uses below method from
> FilterOutputStream
> {code}
> public void close() throws IOException {
> try (OutputStream ostream = out) {
> flush();
> }
> }
> {code}
> Here the flush call caused an IOE to be thrown to here. The finally will
> issue close call on ostream (Which is an instance of BlobOutputStreamInternal)
> When BlobOutputStreamInternal#close() is been called, if there was any
> exception already occured on that Stream, it will throw back the same
> Exception
> {code}
> public synchronized void close() throws IOException {
