-------------------------------------
Summary: Cannot have more than one execute() or executeAsync()
call in a single environment.
Key: FLINK-19754
URL: https://issues.apache.org/jira/browse/FLINK-19754
Project: Flink
Issue Type: Bug
Components: Table SQL / API
Affects Versions: 1.11.2
Environment: my code is:
final StreamExecutionEnvironment env =
StreamExecutionEnvironment.getExecutionEnvironment();
EnvironmentSettings bsSettings =
EnvironmentSettings.newInstance().useBlinkPlanner().inStreamingMode().build();
StreamTableEnvironment tEnv = StreamTableEnvironment.create(env, bsSettings);
...
FlinkKafkaConsumer<String> myConsumer = new
FlinkKafkaConsumer<String>("kafkatopic", new SimpleStringSchema(), properties);
myConsumer.setStartFromLatest();
DataStream<String> kafkaDataStream = env.addSource(myConsumer);
SingleOutputStreamOperator<MessageInfo> sourceStream = kafkaDataStream
.map(new MapFunction<String, MessageInfo>() {
...
});
DataStream<Row> dataStreamRow = sourceStream.map(new
MyMapFunction()).filter(new RuleDataProccessFunction()).map(new
MapFunction<MessageInfo, Row>() {
private static final long serialVersionUID = 1L;
@Override
public Row map(MessageInfo value) throws Exception {
...
}
}).returns(new RowTypeInfo(rowTypeArr, fieldArr));
tEnv.registerFunction("test",new TestFunction());
Table table = tEnv.fromDataStream(dataStreamRow, fieldStr);
tEnv.createTemporaryView("mytable", table);
String ddl = "CREATE TABLE user_log_1155 ...from kafka topic:user_log_1155";
tEnv.executeSql(ddl);
String ddl1 = "CREATE TABLE user_test_1155 ...from kafka topic:user_test_1155";
tEnv.executeSql(ddl);
StatementSet stmtSet = tEnv.createStatementSet();
stmtSet.addInsertSql("INSERT INTO user_log_1155 SELECT xxx from mytable");
stmtSet.addInsertSql("INSERT INTO user_test_1155 SELECT xxx from mytable");
stmtSet.execute();
env.execute(requestPrm.getString("xxx"));
