Flink-1.11.2版本 Filesystem-connector 问题

问题现象是这样的
1. flink 实时的往hdfs 目录 /warehouse/rt_ods/ed_cell_num_info/写数据，以天为分区
2. 然后我们启动了一个定时任务在 hive上新建partition，是T - 1的，比如今天6点执行，新建昨天的分区。
3. 会报，inprogress文件找不到的错误，错误如下 :
```

从上面看出，报错的是pt=20210311的分区里的 inprogress文件找不到。

sql 如下：
```
CREATE TABLE T_ED_CELL_NUM_INFO_SINK(
....
pt STRING
) PARTITIONED BY (pt) WITH (
'connector' = 'filesystem',
'path' = 'hdfs://xxxx/warehouse/rt_ods/ed_cell_num_info',
'format' = 'csv',
'csv.field-delimiter' = U&'\0009',
'csv.disable-quote-character' = 'true',
'sink.rolling-policy.file-size' = '200m',
'sink.rolling-policy.rollover-interval' = '15min',
'sink.rolling-policy.check-interval' = '1min'
);
```
