---------------------------------
Summary: ParquetMetastoreSuite fails when executed together with
other suites under Maven
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}}.
