-------------------------------
Summary: TPCHQuery3 fails due to Serialization issues
Key: FLINK-9399
URL: https://issues.apache.org/jira/browse/FLINK-9399
Project: Flink
Issue Type: Bug
Components: Examples
Affects Versions: 1.5.0
Reporter: Gary Yao
Running {{org.apache.flink.examples.java.relational.TPCHQuery3}} fails because
the static class {{ShippingPriorityItem}} has private visibility, and hence
cannot be serialized.
