             Summary: Fix timezone conversion for timestamp from maprdb after the transition from PDT to PST
                 Key: DRILL-7150
                 URL: https://issues.apache.org/jira/browse/DRILL-7150
             Project: Apache Drill
          Issue Type: Bug
          Components: Storage - MapRDB
    Affects Versions: 1.16.0
            Reporter: Volodymyr Vysotskyi
            Assignee: Volodymyr Vysotskyi
             Fix For: 1.16.0


Steps to reproduce:
0. Set PST timezone and date {{date +%Y%m%d -s "20190329"}}
1. Create the table in MaprDB shell:
{noformat}
create /tmp/testtimestamp
insert /tmp/testtimestamp --value '{"_id":"eot","str":"9999-01-01T23:59:59.999","ts":{"$date":"9999-01-02T07:59:59.999Z"}}'
insert /tmp/testtimestamp --value '{"_id":"pdt","str":"2019-04-01T23:59:59.999","ts":{"$date":"2019-04-02T06:59:59.999Z"}}'
insert /tmp/testtimestamp --value '{"_id":"pst","str":"2019-01-01T23:59:59.999","ts":{"$date":"2019-01-02T07:59:59.999Z"}}'
insert /tmp/testtimestamp --value '{"_id":"unk","str":"2017-07-08T20:01:49.885","ts":{"$date":"2017-07-09T03:01:49.885Z"}}'
{noformat}
2. Create a hive table:
{code:sql}
CREATE EXTERNAL TABLE default.timeTest
(`_id` string,
`str` string,
`ts` 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/timeTest')
{code}
3. Enable native reader and timezone conversion for maprdb timestamp:
{code:sql}
alter session set store.hive.maprdb_json.optimize_scan_with_native_reader=true;
alter session store.hive.maprdb_json.read_timestamp_with_timezone_offset=true;
{code}
4. Run the query on the table from Drill using hive plugin:
{code}
0: jdbc:drill:drillbit=ldevdmhn005:31010> select * from hive.default.timeTest;
+------+--------------------------+--------------------------+
| _id  |           str            |            ts            |
+------+--------------------------+--------------------------+
| eot  | 9999-01-01T23:59:59.999  | 9999-01-02 00:59:59.999  |
| pdt  | 2019-04-01T23:59:59.999  | 2019-04-01 23:59:59.999  |
| pst  | 2019-01-01T23:59:59.999  | 2019-01-02 00:59:59.999  |
| unk  | 2017-07-08T20:01:49.885  | 2017-07-08 20:01:49.885  |
+------+--------------------------+--------------------------+
4 rows selected (0.343 seconds)
{code}

Plese note that the results for {{eot}} and {{pst}} values are wrong.
