-----------------------------------
Resolution: Duplicate
Status: Resolved (was: Patch Available)
[[email protected]] Thanks for working on HADOOP-9565. It looks like a
better solution than this one. I will close this one instead.
[~cnauroth] Sure. I'd love to resolve this as duplicated.
> FileSystem should expose some performance characteristics for caller (e.g.,
> FsShell) to choose the right algorithm.

> 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.
