> It seems some APIs such as {{PairRDDFunctions.saveAsHadoopDataset()}} do not close the record writer before issuing the commit for the task.
> On Windows, the output in the temp directory is being open and output committer tries to rename it from temp directory to the output directory after finishing writing. 
> So, it fails to move the file. It seems we should close the writer actually before committing the task like the other writers such as {{FileFormatWriter}}.
> Identified failure was as below:
> {code}
