yaooqinn opened a new pull request #4149:
URL: https://github.com/apache/iceberg/pull/4149
This PR fixes a minor issue for a jmh test -
`SparkParquetWritersFlatDataBenchmark`
The `dataFile` holds mocked outputs now cleaned at `Level.Trial` which will
be executed after the set of benchmark iterations. Then, it cause errors like
below.
```java
# Warmup Iteration 1: 7.251 s/op
# Warmup Iteration 2: <failure>
org.apache.iceberg.exceptions.AlreadyExistsException: File already exists:
/Users/kentyao/iceberg/spark/v3.2/spark/build/tmp/jmh/parquet-flat-data-benchmark3385433263675547096.parquet
at org.apache.iceberg.Files$LocalOutputFile.create(Files.java:58)
at
org.apache.iceberg.parquet.ParquetIO$ParquetOutputFile.create(ParquetIO.java:148)
```
In this PR, I set the TearDown level to Iteration to make the dataFile be
deleted after each iteration.
