>                 Key: SPARK-3515
>                 URL: https://issues.apache.org/jira/browse/SPARK-3515
>             Project: Spark
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 1.1.1
>            Reporter: Cheng Lian
>
> Reproduction step:
> {code}
> mvn -Phive,hadoop-2.4 -DwildcardSuites=org.apache.spark.sql.parquet.ParquetMetastoreSuite,org.apache.spark.sql.hive.StatisticsSuite -pl core,sql/catalyst,sql/core,sql/hive test
> {code}
> Maven instantiates all discovered test suite object at first, and then starts executing all test cases. {{ParquetMetastoreSuite}} sets up several temporary tables in constructor, but these tables are deleted immediately since {{StatisticsSuite}}'s constructor calls {{TestHiveContext.reset()}}.
> To fix this issue, we shouldn't put this kind of side effect in constructor, but in {{beforeAll}}.
