> ---------------------------------------------------------------
>
> Key: FLINK-35698
> URL: https://issues.apache.org/jira/browse/FLINK-35698
> Project: Flink
> Issue Type: Bug
> Components: Formats (JSON, Avro, Parquet, ORC, SequenceFile), Table
> SQL / API
> Affects Versions: 1.17.0, 1.18.0, 1.19.0
> Reporter: Andrey Gaskov
> Priority: Critical
> Fix For: 2.0.0
>
>
> The bug could be reproduced by the following test added to
> ParquetFileSystemITCase.java:
> {code:java}
> @TestTemplate
> void testRowColumnType() throws IOException, ExecutionException,
> InterruptedException {
> String path =
> TempDirUtils.newFolder(super.fileTempFolder()).toURI().getPath();
> super.tableEnv()
> .executeSql(
> "create table t_in("
> + "grp ROW<x decimal(5, 2)>"
> + ") with ("
> + "'connector' = 'datagen',"
> + "'number-of-rows' = '10'"
> + ")");
> super.tableEnv()
> .executeSql(
> "create table t_out("
> + "grp ROW<x decimal(5, 2)>"
> + ") with ("
> + "'connector' = 'filesystem',"
> + "'path' = '"
> + path
> + "',"
> + "'format' = 'parquet'"
> + ")");
> super.tableEnv().executeSql("insert into t_out select * from
> t_in").await();
> List<Row> rows =
> CollectionUtil.iteratorToList(
> super.tableEnv().executeSql("select * from t_out limit
> 10").collect());
> assertThat(rows).hasSize(10);
> } {code}
> It fails with this root exception after hanging for 40 seconds:
> {code:java}
