> When running {{hadoop fs -put}}, {{FsShell}} creates a {{._COPYING_.}} file
> on the target directory, and then renames it to target file when the write is
> done. However, for some targeted systems, such as S3, Azure and Swift, a
> partial failure write request (i.e., {{PUT}}) has not side effect, while the
> {{rename}} operation is expensive.
> {{FileSystem}} should expose some characteristics so that the operation such
> as {{CommandWithDestination#copyStreamToTarget()}} can detect and choose the
> right way to do.
