             Summary: Inconsistent results when reading MaprDB JSON tables using hive plugin when native reader is enabled
                 Key: DRILL-6969
                 URL: https://issues.apache.org/jira/browse/DRILL-6969
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 1.14.0
            Reporter: Volodymyr Vysotskyi
            Assignee: Volodymyr Vysotskyi
             Fix For: 1.16.0


Steps to reproduce:
0. Set PST timezone.
1. Create the table in MaprDB shell:
{code}
create /tmp/testtimestamp
insert /tmp/testtimestamp --value '{"_id":"1","datestring":"2018-01-01 12:12:12.123","datetimestamp":{"$date":"2018-01-01T20:12:12.123Z"}}'
insert /tmp/testtimestamp --value '{"_id":"2","datestring":"9999-12-31 23:59:59.999","datetimestamp":{"$date":"10000-01-01T07:59:59.999Z"}}'
{code}
2. Create a hive table:
{code:sql}
create external table `testtimestamp` (`_id` string, datestring string, datetimestamp timestamp)
ROW FORMAT SERDE 'org.apache.hadoop.hive.maprdb.json.serde.MapRDBSerDe'
STORED BY 'org.apache.hadoop.hive.maprdb.json.MapRDBJsonStorageHandler'
TBLPROPERTIES ( 'maprdb.column.id'='_id', 'maprdb.table.name'='/tmp/testtimestamp');
{code}
3. Disable native reader and run the query on the table from Drill using hive plugin:
{code:sql}
alter session set store.hive.maprdb_json.optimize_scan_with_native_reader=false;
select * from hive.testtimestamp;
{code}
It returns:
{noformat}
+------+--------------------------+--------------------------+
| _id  |        datestring        |      datetimestamp       |
+------+--------------------------+--------------------------+
| 1    | 2018-01-01 12:12:12.123  | 2018-01-01 12:12:12.123  |
| 2    | 9999-12-31 23:59:59.999  | 9999-12-31 23:59:59.999  |
+------+--------------------------+--------------------------+
{noformat}
4. Enable native reader and run the query on the same table:
{code:sql}
alter session set store.hive.maprdb_json.optimize_scan_with_native_reader=true;
select * from hive.testtimestamp;
{code}
It returns:
{noformat}
+------+--------------------------+---------------------------+
| _id  |        datestring        |       datetimestamp       |
+------+--------------------------+---------------------------+
| 1    | 2018-01-01 12:12:12.123  | 2018-01-01 20:12:12.123   |
| 2    | 9999-12-31 23:59:59.999  | 10000-01-01 07:59:59.999  |
+------+--------------------------+---------------------------+
{noformat}
