-------------------------------------
Summary: Regression: Schema evolution of union containing array
fails in 1.9.0
Key: AVRO-2415
URL: https://issues.apache.org/jira/browse/AVRO-2415
Project: Apache Avro
Issue Type: Bug
Components: java
Affects Versions: 1.9.0
Reporter: Martin Jubelgas
Assignee: Martin Jubelgas
I've come across another example that does not resolve in 1.9.0 but did in
1.8.2:
{code:java}
public void testArrayInUnion() throws Exception {
Schema writerSchema = SchemaBuilder.array().items().intType();
Schema readerSchema = SchemaBuilder.unionOf()
.nullType()
.and()
.array().items().intType().endUnion();
ResolvingDecoder.resolve(writerSchema, readerSchema );
}
{code}
results in just the same kind of exception (even with pull request #526 applied)
{code:java}
java.lang.ClassCastException: org.apache.avro.Resolver$ReaderUnion cannot be
cast to org.apache.avro.Resolver$Container
