> Hive's MoveTask uses the Hive.moveFile method to move data within a
> distributed filesystem as well as blobstore filesystems.
> If the move is done within the same filesystem:
> 1: If the source path is a subdirectory of the destination path, files will
> be moved one by one using a threapool of workers
> 2: If the source path is not a subdirectory of the destination path, a single
> rename operation is used to move the entire directory
> The second option may not work well on blobstores such as S3. Renames are not
> metadata operations and require copying all the data. Client connectors to
> blobstores may not efficiently rename directories. Worst case, the connector
> will copy each file one by one, sequentially rather than using a threadpool
> of workers to copy the data (e.g. HADOOP-13600).
> Hive already has code to rename files using a threadpool of workers, but this
> only occurs in case number 1.
> This JIRA aims to modify the code so that case 1 is triggered when copying
> within a blobstore. The focus is on copies within a blobstore because
> needToCopy will return true if the src and target filesystems are different,
> in which case a different code path is triggered.
