Flink SQL 写入Hive问题请教

我们在开发一个Flink SQL 框架，在从kafka读取数据加工写入到Hive时一直不成功，sql脚本如下：
CREATE TABLE hive_table_from_kafka (
collect_time STRING,
content1 STRING,
content2 STRING
) PARTITIONED BY (
dt STRING,hr STRING
) TBLPROPERTIES (
'partition.time-extractor.timestamp-pattern'='$dt $hr',
'sink.partition-commit.trigger'='partition-time',
'sink.partition-commit.delay'='0S',
'sink.partition-commit.policy.kind'='metastore,success-file'
);

然后代码中对于创建表的sql做如下的处理
private void callCreateTable(SqlCommandParser.SqlCommandCall cmdCall) {
String ddl = cmdCall.operands[0];
if (ddl.contains("hive_table")) {
tableEnv.getConfig().setSqlDialect(SqlDialect.HIVE);
} else {
tableEnv.getConfig().setSqlDialect(SqlDialect.DEFAULT);
}
try {
tableEnv.executeSql(ddl);
} catch (SqlParserException e) {
throw new RuntimeException("SQL execute failed:\n" + ddl + "\n", e);
}
}在执行上面的SQL语句时，总是报没有设置connector:Caused by: org.apache.flink.table.api.ValidationException: Table options do not contain an option key 'connector' for discovering a connector

Re: Flink SQL 写入Hive问题请教

你这没有把dialect set成hive吧，走到了else分支。default
dialect是需要指定connector的，参考文档的kafka到hive代码

Re:Re: Flink SQL 写入Hive问题请教

我增加调试日志后，发现执行DDL语句创建hive表时，设置了dialect 为hive,现在报错根据堆栈信息是在执行DML语句insert into时创建Hive表时提示没有连接器的配置

假如在执行DML语句时设置Hive方言，那么Kafka的表不是Hive语法，这个该怎么处理？

Re: Re:Re: Flink SQL 写入Hive问题请教

在hive catalog下创建kafka source表会在hive
metastore中创建一张仅包含元数据的表，hive不可查，flink任务中可以识别并当成hive表读，然后只需要在hive
dialect下正常读出写入即可。

你好，

用的flink是什么版本呢？另外这张hive表是创建在HiveCatalog里的么？

Re: Re: Flink SQL 写入Hive问题请教

Flink的版本是1.11.3，目前我们所有表的catalog类型都是GenericInMemoryCatalog，是不是Hive表要用HiveCatalog才行？

Re: Re: Flink SQL 写入Hive问题请教

是的，hive表必须存在HiveCatalog里才能正常读写
