   > FYI, we run ThriftServerQueryTestSuite - SQL tests in 
sql/core/src/test/resources/sql-tests under Java 8 time API ON but 
SQLQueryTestSuite with Java 8 time API OFF. So, we run the same tests for both 
values of spark.sql.datetime.java8API.enabled.
   
   There is another difference in that SQLQueryTestSuite runs with Spark 
Dataframe API, so you collect the results directly using the Spark APIs, while 
ThriftServerQueryTestSuite runs it via JDBC connection and via Hive JDBC 
driver, so Date/Timestamps are being printed to string, and parsed back from 
String into java.sql.Date / java.sql.Timestamp by the Hive JDBC driver.
   So there is more differences than one running with Java 8 API ON, and the 
other with OFF.
