Kenneth Knowles updated BEAM-10395:
-----------------------------------
Status: Open (was: Triage Needed)
> Dataflow runner should deduplicate files to stage by destination
> -----------------------------------------------------------------
>
> Key: BEAM-10395
> URL: https://issues.apache.org/jira/browse/BEAM-10395
> Project: Beam
> Issue Type: Improvement
> Components: runner-dataflow
> Reporter: Steve Niemitz
> Assignee: Steve Niemitz
> Priority: P2
>
> If a pipeline contains multiple files with the same destination path, the
> dataflow runner will try to stage them both in parallel, resulting in the
> upload usually failing (due to conflicting uploads).
> The runner should only upload one file per destination, and ideally check
> that the sources are the same as well.
