-----------------------------------
Summary: FlinkSQL1.12 Sink to Hive with diffrent parallelism will
due to produce many small files
Key: FLINK-22897
URL: https://issues.apache.org/jira/browse/FLINK-22897
Project: Flink
Issue Type: Improvement
Affects Versions: 1.12.1
Reporter: zhengjiewen
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
{code}
INSERT OVERWRTITE 【targetTable】SELECT 【field】FROM 【sourceTable】;
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.
