> 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.
