----------------------------------
Summary: AvroUtils.schemaCoder(schema) produces a not serializable
SchemaCoder
Key: BEAM-9042
URL: https://issues.apache.org/jira/browse/BEAM-9042
Project: Beam
Issue Type: Bug
Components: sdk-java-core
Affects Versions: 2.18.0
Reporter: Ismaël Mejía
Assignee: Ismaël Mejía
After some recent change in the implementation of AvroUtils.schemaCoder(schema)
the produced SchemaCoder is not serializable.
You can reproduce this by doing this:
{code:java}
final SchemaCoder<GenericRecord> avroSchemaCoder =
AvroUtils.schemaCoder(schema);
CoderProperties.coderSerializable(avroSchemaCoder);{code}
it produces this exception
{code:java}
