Sergio Peña commented on HIVE-14271:
------------------------------------
Agree with approach #2. If outPath and finalPath are scratch directories, then
we can just write directly to finalPath and avoid the rename.
[~ste...@apache.org] There is another patch to do S3-to-S3 renames in parallel
to speed up the COPY operations (See HIVE-15093)
> FileSinkOperator should not rename files to final paths when S3 is the
> default destination

> FileSinkOperator does a rename of {{outPaths -> finalPaths}} when it finished
> writing all rows to a temporary path. The problem is that S3 does not support
> renaming.
> Two options can be considered:
> a. Use a copy operation instead. After FileSinkOperator writes all rows to
> outPaths, then the commit method will do a copy() call instead of move().
> b. Write row by row directly to the S3 path (see HIVE-1620). This may add
> better performance calls, but we should take care of the cleanup part in case
> of writing errors.
