      Description

      Query on a parquet backed table returns different results based on value of hive.optimize.ppd.storage.

      Steps to reproduce:

      CREATE TABLE `test_table`(
      `some_value` int)
      PARTITIONED BY (
      `date` string,
      `id` int)
      ROW FORMAT SERDE
      'org.apache.hadoop.hive.ql.io.parquet.serde.ParquetHiveSerDe'
      STORED AS INPUTFORMAT
      'org.apache.hadoop.hive.ql.io.parquet.MapredParquetInputFormat'
      OUTPUTFORMAT
      'org.apache.hadoop.hive.ql.io.parquet.MapredParquetOutputFormat';

      set hive.exec.dynamic.partition.mode=nonstrict;

      insert into test_table PARTITION (date, id) VALUES (12, '2017-04-09', 16), (13, '2017-04-09', 32), (NULL, '2017-04-09', 51), (23, '2017-04-09', 51), (66, '2017-04-09', 16), (17, '2017-04-09', 32), (NULL, '2017-04-09', 32);

      SELECT distinct id from test_table WHERE id IN (16, 32, 51) AND date = '2017-04-09' AND (id!=32 OR some_value IS NULL);
      -----+

      id

      -----+

      32
      51

      (incorrect)

      Can be fixed with:
      set hive.optimize.ppd.storage=false;

      -----+

      id

      -----+

      16
      32
      51

      -----+
      (correct)

      Can also be fixed with ..... (id!=32 OR some_value IS NULL)=true;
      and replacing or with and fixes.
