Jark Wu created FLINK-18539:
-------------------------------
Summary: StreamExecutionEnvironment#addSource(SourceFunction,
TypeInformation) doesn't use the user defined type information
Key: FLINK-18539
URL: https://issues.apache.org/jira/browse/FLINK-18539
Project: Flink
Issue Type: Task
Affects Versions: 1.11.0
Reporter: Jark Wu
Fix For: 1.12.0, 1.11.1
{code:java}
class MySource<T> implements SourceFunction<T>, ResultTypeQueryable<T> {
TypeInformation getProducedType() {
return TypeExtractor.createTypeInfo(SourceFunction.class, this.getClass(),
0, null, null);
}
}
DataStream ds = tEnv.addSource(new MySource(), Types.ROW(Types.STRING))
{code}
The returned {{TypeInformation}} of {{MySource}} is {{GenericTypeInfo}}, not
the user given {{RowTypeInfo}}.
It seems that {{StreamExecutionEnvironment#getTypeInfo}} doesn't use the user
given {{typeInfo}} in the highest priority.
