-----------------------------------------------------------------
Maybe a solution is checking whether any AWS-specific options are actually
given in *S3FileSystemRegistrar.java* and, if not, return an empty list.

> Reporter: Samuel Waggoner
> Assignee: Ismaël Mejía
> Priority: Major

> I want my pipeline to support writing to S3, but I also want it to work
> locally when a user doesn't specify any S3-specific options. Instead, I get
> the following exception:
> {code:java}
> com.amazonaws.SdkClientException: Unable to find a region via the region
> provider chain. Must provide an explicit region in the builder or setup
> environment to supply a region. E at
> com.amazonaws.client.builder.AwsClientBuilder.setRegion(AwsClientBuilder.java:371){code}
> I had thought that I should use a single PipelineOptions interface that
> supports all available options for my pipeline. Is this wrong? Should using
> an instance of S3Options for my pipeline options force the user to write to
> s3 (or otherwise provide s3 options).
> Should I choose a PipelineOptions subinterface based on the options the user
> tries to use at runtime?
