Luke Cwik reassigned BEAM-3502:
-------------------------------
Assignee: Larry Li (was: Kenneth Knowles)
> Avoid use of proto.Builder.clone() in DatastoreIO
> -------------------------------------------------
>
> Key: BEAM-3502
> URL: https://issues.apache.org/jira/browse/BEAM-3502
> Project: Beam
> Issue Type: Improvement
> Components: beam-model
> Affects Versions: 2.2.0
> Reporter: Larry Li
> Assignee: Larry Li
> Priority: Minor
> Fix For: 2.3.0
>
>
> DatastoreIO uses proto.Builder.clone() here:
> [https://github.com/apache/beam/blob/c0f0e1fd63ce1e9dfe1db71adf1c8b9e88ce7038/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/datastore/DatastoreV1.java#L893]
>
> It's only used in one place for actual runtime code, but this causes
> incompatibility problems with Google-internal Java proto generation, i.e. we
> get a 'NoSuchMethodError' when attempting to run the pipeline with internal
> build tools.
>
> This is a known problem that's already been worked around once:
> https://issues.apache.org/jira/browse/BEAM-2392
> ..but the fix only applied to BigtableServiceImpl. This extends those changes
> to DatastoreIO, replacing its single use of clone(). Associated tests
> shouldn't need refactoring, as this only appears as a problem at runtime.
