flink-1.11 hive-1.2.1 ddl 无法写入数据

确认数据源有数据,全部代码如下,但是hive就是没有数据

package com.hive;

StreamExecutionEnvironment env = StreamExecutionEnvironment.getExecutionEnvironment();

env.setParallelism(1);

env.setStreamTimeCharacteristic(TimeCharacteristic.ProcessingTime);

// 同一时间只允许进行一个检查点

env.getCheckpointConfig().setMaxConcurrentCheckpoints(1);

env.setStateBackend(new FsStateBackend(path));

EnvironmentSettings tableEnvSettings = EnvironmentSettings.newInstance()

.inStreamingMode()

.build();

StreamTableEnvironment tableEnv = StreamTableEnvironment.create(env,tableEnvSettings);

tableEnv.getConfig().getConfiguration().set(ExecutionCheckpointingOptions.CHECKPOINTING_MODE, CheckpointingMode.EXACTLY_ONCE);

tableEnv.getConfig().getConfiguration().set(ExecutionCheckpointingOptions.CHECKPOINTING_INTERVAL, Duration.ofSeconds(20));

String name = "myhive";

String defaultDatabase = "situation";

String hiveConfDir = "/load/data/hive/hive-conf"; // a local path

String version = "1.2.1";

HiveCatalog hive = new HiveCatalog(name, defaultDatabase, hiveConfDir, version);

tableEnv.registerCatalog("myhive", hive);

// set the HiveCatalog as the current catalog of the session

tableEnv.useCatalog("myhive");

tableEnv.executeSql("CREATE DATABASE IF NOT EXISTS situation");

tableEnv.executeSql("DROP TABLE IF EXISTS situation.source_table");

tableEnv.executeSql("CREATE TABLE situation.source_table (\n" +

tableEnv.getConfig().setSqlDialect(SqlDialect.HIVE);

tableEnv.executeSql("DROP TABLE IF EXISTS situation.fs_table");

String hiveSql = "\n" +
