> HADOOP-12334 changed mode of Copy Operation of HBase WAL Archiving to bypass
> Azure Storage Throttling after retries. This was via client side copy.
> However a process crash when the copy is partially done would result in a
> scenario where the source and destination blobs will have different contents
> and lazy rename pending operation will not handle this thus causing data
> loss. We need to fix the lazy rename pending operation to address this issue
