Change subject: IMPALA-8110: Fix the Parquet stats filtering issue to correctly handle narrowed integer types ...................................................................... IMPALA-8110: Fix the Parquet stats filtering issue to correctly handle narrowed integer types This patch adds validation for the paired stats values of tinyint and smallint column data type when reading min/max column stats value from Parquet file. Testing: - Did Manual tests: create table with column as int type, intert some values, then alter table to change the column data type as tinyint (int8), insert more values, verify that the query return correct number of rows when PARQUET_READ_STATISTICS is set as 1. Did similar tests to change column data type from int to smallint, and from smallint to tinyint. - Added automatic test cases in parquet-stats.test for column data type been changed from int to tinyint, from smallint to tinyint and from int to smallint. - Passed EE tests. - Passed all core tests.
