Chesnay Schepler created FLINK-10235:
----------------------------------------
Summary: KafkaTableSourceSinkFactoryBase#getFlinkKafkaPartitioner
does not compile with Java 9
Key: FLINK-10235
URL: https://issues.apache.org/jira/browse/FLINK-10235
Project: Flink
Issue Type: Sub-task
Components: Table API & SQL
Affects Versions: 1.7.0
Reporter: Chesnay Schepler
Assignee: Chesnay Schepler
Fix For: 1.7.0
The method compilation fails on java 9. The problem is that the
{{CONNECTOR_SINK_PARTITIONER_VALUE_CUSTOM}} branch returns an
{{Optional<Class<? extends FlinkKafkaPartitioner>>}}, but the method requires a
{{Optional<FlinkKafkaPartitioner<Row>>}}.
{code}
private Optional<FlinkKafkaPartitioner<Row>>
getFlinkKafkaPartitioner(DescriptorProperties descriptorProperties) {
return descriptorProperties
.getOptionalString(CONNECTOR_SINK_PARTITIONER)
.flatMap((String partitionerString) -> {
switch (partitionerString) {
case CONNECTOR_SINK_PARTITIONER_VALUE_FIXED:
return Optional.of(new
FlinkFixedPartitioner<>());
case
CONNECTOR_SINK_PARTITIONER_VALUE_ROUND_ROBIN:
return Optional.empty();
case CONNECTOR_SINK_PARTITIONER_VALUE_CUSTOM:
final Class<? extends
FlinkKafkaPartitioner> partitionerClass =
descriptorProperties.getClass(CONNECTOR_SINK_PARTITIONER_CLASS,
FlinkKafkaPartitioner.class);
return
Optional.of(InstantiationUtil.instantiate(partitionerClass));
default:
throw new TableException("Unsupported
sink partitioner. Validator should have checked that.");
}
});
}
{code}
