[hivewriter] with partition result with empty data

See original GitHub issue

my flinkx config with kafkareader and hivewriter like this

{
    "job": {
        "content": [
            {
                "reader": {
                    "parameter": {

                                "type": "string"
                            }
                        ]
                    },
                    "name": "kafkareader"
                },
                "writer": {

                        "partition": "pt_mi",
                        "partitionType": "MINUTE",

                    },
                    "name": "hivewriter"
                }
            }
        ],
        "setting": {
            "restore": {
                "isRestore": false,
                "isStream": false
            },
            "speed": {
                "readerChannel": 1,
                "writerChannel": 1
            }
        }
    }
}

and the table and partition path is created in hdfs. but the data path is empty, no parquet file exist;

spark-sql> dfs -du -h  /user/hive/warehouse/demo.db/flinkx_test;
0  /user/hive/warehouse/demo.db/flinkx_test/pt_mi=202105251620
0  /user/hive/warehouse/demo.db/flinkx_test/pt_mi=202105251621
0  /user/hive/warehouse/demo.db/flinkx_test/pt_mi=202105251622
spark-sql>

so why the data not write in the path.

I　use this kafka reader cant write to mysql, but not working with hivewrite.

any idea would be appreciated!
