> Druid Queries containing Joins gives wrong results.

> Key: HIVE-19762
> URL: https://issues.apache.org/jira/browse/HIVE-19762
> Project: Hive
> Issue Type: Bug
> Components: Druid integration

> Druid queries that have joins against self table gives wrong results.
> e.g.
> {code}
> SELECT
> username AS `username`,
> SUM(double1) AS `sum_double1`
> FROM
> druid_table_with_nulls `tbl1`
> JOIN (
> SELECT
> username AS `username`,
> SUM(double1) AS `sum_double2`
> FROM druid_table_with_nulls
> GROUP BY `username`
> ORDER BY `sum_double2`
> DESC LIMIT 10
> )
> `tbl2`
> ON (`tbl1`.`username` = `tbl2`.`username`)
> GROUP BY `tbl1`.`username`;
> {code}
> In this case one of the queries is a druid scan query and other is groupBy
> query.
> During planning, the properties of these queries are set to the tableDesc and
> serdeInfo, while setting the map work, we overwrite the properties from the
> properties present in serdeInfo, this causes the scan query results to be
> deserialized using wrong column names and results in Null values.
