> 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
> Priority: Major
> Labels: doc-impacting, ready-to-commit
> Fix For: 1.16.0
>
>
> Steps to reproduce:
> 0. Set PST timezone.
> 1. Create the table in MaprDB shell:
> {code:java}
> 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}
> h2. For documentation:
> Added the following Mapr-DB Format Setting:
> ||Option||Description||Value||
> |readTimestampWithZoneOffset|When enabled, Drill converts timestamp values
> read form MapR Database from UTC to local timezone. Disabled by
> default.|true\|false|
> Added the following configuration option:
> ||Name||Default||Description||
> |store.hive.maprdb_json.read_timestamp_with_timezone_offset|FALSE|Enables
> Drill to read timestamp values with timezone offset when hive plugin is used
> and Drill native MaprDB JSON reader usage is enabled. (Drill 1.16+)|
