Hongbo created FLINK-24926:
------------------------------
Summary: Key group is not in KeyGroupRange when joining two
streams with table API
Key: FLINK-24926
URL: https://issues.apache.org/jira/browse/FLINK-24926
Project: Flink
Issue Type: Bug
Components: Table SQL / Runtime
Affects Versions: 1.14.0
Reporter: Hongbo
I have a simple test to join two streams by the event time:
{code:java}
@Test
void testJoinStream() {
var settings = EnvironmentSettings
.newInstance()
.inStreamingMode()
.build();
var tableEnv = TableEnvironment.create(settings);
var configuration = tableEnv.getConfig().getConfiguration();
configuration.setString("table.exec.resource.default-parallelism", "2");
var testTable = tableEnv.from(TableDescriptor.forConnector("datagen")
.schema(Schema.newBuilder()
.column("ts", DataTypes.TIMESTAMP(3))
.column("v", DataTypes.INT())
.watermark("ts", "ts - INTERVAL '1' second")
.build())
.option(DataGenConnectorOptions.ROWS_PER_SECOND, 2L)
.option("fields.v.kind", "sequence")
.option("fields.v.start", "0")
.option("fields.v.end", "1000000")
.build());
testTable.printSchema();
tableEnv.createTemporaryView("test", testTable );
var joined = tableEnv.sqlQuery("SELECT ts, v, v2 from test" +
" join (SELECT ts as ts2, v as v2 from test) on ts = ts2");
try {
var tableResult =
joined.executeInsert(TableDescriptor.forConnector("print").build());
tableResult.await();
} catch (InterruptedException | ExecutionException e) {
throw new RuntimeException(e);
}
} {code}
It failed within a few seconds:
{code:java}

What is the problem? The error message is not intuitive and I couldn't find
what caused the problem.
I saw the Exception is reported by others such as
https://issues.apache.org/jira/browse/FLINK-18637 . But those are using
DataStream APIs.
