> Key: FLINK-22897
> URL: https://issues.apache.org/jira/browse/FLINK-22897
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / Ecosystem
> Affects Versions: 1.12.1
> Reporter: zhengjiewen
> Priority: Critical
> Labels: stale-critical
> Fix For: 1.14.0
>
>
> I try to use flink sql in batch mode, to sink data into hive partition table,
> here is the sql:
>
> {code:java}
> //代码占位符
> INSERT OVERWRTITE 【targetTable】SELECT 【field】FROM 【sourceTable】;
> {code}
>
>
>
> And I found that when the parallelism of the sink operator is different from
> that of the operator before it, a large number of small files will be
> generated. But this is not the case when the parallelism is the same.
