> I’m getting the following error when attempting to use the FileIO apis
> (beam-2.15.0) and integrating with AWS S3. I have setup the PipelineOptions
> with all the relevant AWS options, so the filesystem registry **should** be
> properly seeded by the time the graph is compiled and executed:
> {code:java}

> For reference, the write code resembles this:
> {code:java}
> FileIO.Write<?, GenericRecord> write = FileIO.<GenericRecord>write()
> .via(ParquetIO.sink(schema))
> .to(options.getOutputDir()). // will be something like:
> s3://<bucket>/<path>
> .withSuffix(".parquet");
> records.apply(String.format("Write(%s)", options.getOutputDir()),
> write);{code}
> The issue does not appear to be related to ParquetIO.sink(). I am able to
> reliably reproduce the issue using JSON formatted records and TextIO.sink(),
> as well. Moreover, AvroIO is affected if withWindowedWrites() option is
> added.
> Just trying some different knobs, I went ahead and set the following option:
> {code:java}
> write = write.withNoSpilling();{code}
> This actually seemed to fix the issue, only to have it reemerge as I scaled
> up the data set size. The stack trace, while very similar, reads:
> {code:java}

> And lastly, I tried adding the following deprecated option (with and without
> the withNoSpilling() option):
> {code:java}
> write = write.withIgnoreWindowing(); {code}
> This seemed to fix the issue altogether but aside from having to rely on a
> deprecated feature, there is the bigger issue of why?
>
> In reading through some of the source, it seems a common pattern to have to
> manually register the pipeline options to seed the filesystem registry during
> the setup part of the operator lifecycle, e.g.:
