Kenneth Knowles updated BEAM-10295:
-----------------------------------
Priority: P1 (was: P3)
> FileBasedSink: allow setting temp directory provider per dynamic destination
> ----------------------------------------------------------------------------
>
> Key: BEAM-10295
> URL: https://issues.apache.org/jira/browse/BEAM-10295
> Project: Beam
> Issue Type: Bug
> Components: io-java-hadoop-file-system, sdk-java-core
> Reporter: David Janicek
> Priority: P1
> Labels: Clarified
>
> Dynamic file destinations allow value-dependent writes in FileBasedSink. When
> using hadoop file system this means user can write some values to destination
> at *cluster-A* and some values to destination at *cluster-B*.
> Since BEAM-7613 was fixed this works fine until the *moveToOutputFiles*
> method is called. This method internally calls *FileSystems.rename* which
> obviously requires that source files (temporary files) and target files
> (resolved by dynamic destination's function) are on the same cluster. But the
> temp directory provider can be set only one per file sink.
> This could be fixed by adding some kind of *getTempDirectoryProvider* method
> into dynamic destinations (e.g. into *DefaultFilenamePolicy.Params*).
