> In YARN-9525, we made IFile format compatible with remote folders with s3a
> scheme. In rolling fashioned log-aggregation IFile still fails with the
> "append is not supported" error message, which is a known limitation of the
> format by design.
> There is a workaround though: setting the rollover size in the configuration
> of the IFile format, in each rolling cycle a new aggregated log file will be
> created, thus we eliminated the append from the process. Setting this config
> globally would cause performance problems in the regular log-aggregation, so
> I'm suggesting to enforcing this config to zero, if the scheme of the URI is
> s3a (or any other non-appendable filesystem).
