> Refactor FileTablespace::commitOutputData.
> ------------------------------------------

> Key: TAJO-2063

> Components: Storage

>
> {{FileTablespace::commitOutputData}} has some problems as following:
> First, it is too long and complexed because it handles various cases in a
> single method. We need to refactor this method into several small and
> well-defined methods.
> Second, {{FileSystem::listStatus}} is widely used while committing output
> data. It especially causes a lot of overhead to list partitioned directories
> in S3. Also it occurs in HDFS too with large partitioned tables. We need to
> minimize its usage.
