-------------------------------------
Assignee: (was: Stephen Sisk)
> Source.getDefaultOutputCoder() - add a version that allows access to a
> CoderRegistry
> ------------------------------------------------------------------------------------
>
> Key: BEAM-1171
> URL: https://issues.apache.org/jira/browse/BEAM-1171
> Project: Beam
> Issue Type: Bug
> Components: sdk-java-core
> Reporter: Stephen Sisk
> Fix For: First stable release
>
>
> The Source API's getDefaultOutputCoder currently takes no parameters. This
> means that you can't access the coder registry to ask for coders based on the
> type.
> The PTransform API's version of getDefaultOutputCoder has 3 different form,
> which do allow access to the coder registry if necessary.
> However, while working on BEAM-1040 (Hadoop IO connector), we realized that a
> source does not always know it's output type, and thus will need to calculate
> the coder at run time. To do this, it would be helpful to have a reference to
> the CoderRegistry - we should look at what we're doing on PTransform and
> decide if we should port that over onto Source.
