flink 1.12.0 FileSystem 读取 hdfs 文件，什么原因？
Flink 1.12.0中 Filesystem 读取 hdfs orc文件，但是数据没有打印出来，各位大佬这是什么原因导致的？EnvironmentSettings settings = EnvironmentSettings.newInstance().useBlinkPlanner().inBatchMode().build(); TableEnvironment tableEnv = TableEnvironment.create(settings); String createSql = "CREATE TABLE test_jds_table (" + " dc__key Int," + " name String," + " c4 String," + " dc__time String" + ") WITH (" + " 'connector' = 'filesystem'," + " 'path' = 'hdfs://HDFS41645/usr/hive/warehouse/tmp.db/test_jds_table_d839cd09f5cc44dba8f45eee0d282ee3'," + " 'format' = 'orc'" + ")"; String createPrintTableSql = "CREATE TABLE print_table WITH ('connector' = 'print') LIKE test_jds_table (EXCLUDING ALL)"; String insertSql = "insert into print_table select * from test_jds_table"; tableEnv.executeSql(createSql); tableEnv.executeSql(createPrintTableSql); tableEnv.executeSql(insertSql);*来自志愿者整理的flink

你好， tableEnv.executeSql对DQL和DML是异步执行的，要等作业结束可以用tableEnv.executeSql.await*来自志愿者整理的flink
