> Key: SPARK-4764
> URL: https://issues.apache.org/jira/browse/SPARK-4764
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 1.1.0
> Reporter: Christophe PRÉAUD
> Assignee: Christophe PRÉAUD
> Priority: Minor
> Labels: backport-needed
> Fix For: 1.3.0, 1.1.2, 1.2.1
>
>
> It does not seem necessary in the {{doFetchFile}} method to first download
> the file into a local directory then move it (it may cause a copy instead of
> a rename).
> {{tempFile}} (where the file is downloaded) should be created in the same
> directory than {{targetFile}}, so that the move from {{tempFile}} to
> {{targetFile}} is always atomic
