### Search before asking - [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues. ### Version 1ba20b1dbb4310c72f55f7834938e6ca40b21026 ### What's Wrong? When using select into outfile, the error `Empty partition info` is occasionally reported. ### What You Expected? Query normally. ### How to Reproduce? 1. Create table ```sql CREATE TABLE `t1` ( `id` int(11) NOT NULL DEFAULT "0" COMMENT "", `stream` text NOT NULL DEFAULT "" COMMENT "" ) ENGINE=OLAP DUPLICATE KEY(`id`, `stream`) COMMENT "OLAP" DISTRIBUTED BY HASH(`stream`) BUCKETS 1 PROPERTIES ( "replication_allocation" = "tag.location.default: 1", "in_memory" = "false", "storage_format" = "V2" ); ``` 2. Insert some data 3. Select into outfile ```sql select * from t1 INTO OUTFILE 'hdfs://path_to_file' FORMAT AS CSV PROPERTIES ( "broker.name" = 'xxx', "broker.username" = 'xxx', "broker.password" = 'xxx', "column_separator" = ',', "max_file_size" = '1024M' ); ``` 4. Query repeatly. ### Anything Else? It is because `DataSink::create_data_sink` creates `ResultFileSink`, and then executes `sink->init()`. `ResultFileSink` inherits from `DataStreamSender`, but does not rewrite the `init` method, which causes the method of the parent class `DataStreamSender` to be called. Because the parent class is not initialized, resulting in `_part_type` value is random, and an error will be reported occasionally. . ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
