Eugene Kirpichov reassigned BEAM-2712:
--------------------------------------
Assignee: (was: Kenneth Knowles)
> SerializablePipelineOptions should not call
> FileSystems.setDefaultPipelineOptions.
> ----------------------------------------------------------------------------------
>
> Key: BEAM-2712
> URL: https://issues.apache.org/jira/browse/BEAM-2712
> Project: Beam
> Issue Type: Bug
> Components: runner-apex, runner-core, runner-flink, runner-spark
> Reporter: Eugene Kirpichov
>
> https://github.com/apache/beam/pull/3654 introduces
> SerializablePipelineOptions, which on deserialization calls
> FileSystems.setDefaultPipelineOptions.
> This is obviously problematic and racy in case the same process uses
> SerializablePipelineOptions with different filesystem-related options in them.
> The reason the PR does this is, Flink and Apex runners were already doing it
> in their respective SerializablePipelineOptions-like classes (being removed
> in the PR); and Spark wasn't but probably should have.
> I believe this is done for the sake of having the proper filesystem options
> automatically available on workers in all places where any kind of
> PipelineOptions are used. Instead, all 3 runners should pick a better place
> to initialize their workers, and explicitly call
> FileSystems.setDefaultPipelineOptions there.
> It would be even better if FileSystems.setDefaultPipelineOptions didn't exist
> at all, but that's a topic for a separate JIRA.
