-----------------------------------------
[~jcamachorodriguez] Can this be closed , since CALCITE-1577 is resolved ?
> Hive/Druid integration: Incorrect result - Limit on timestamp disappears
> ------------------------------------------------------------------------
>
> Key: HIVE-15632
> URL: https://issues.apache.org/jira/browse/HIVE-15632
> Project: Hive
> Issue Type: Bug
> Components: Druid integration
> Affects Versions: 2.2.0
> Reporter: Jesus Camacho Rodriguez
> Assignee: Jesus Camacho Rodriguez
> Priority: Critical
>
> This can be observed with the following query:
> {code:sql}
> SELECT DISTINCT `__time`
> FROM store_sales_sold_time_subset_hive
> ORDER BY `__time` ASC
> LIMIT 10;
> {code}
> Query is translated correctly to Druid _timeseries_, but _limit_ operator
> disappears.
> {code}
> OK
> Plan optimized by CBO.
> Stage-0
> Fetch Operator
> limit:-1
> Select Operator [SEL_1]
> Output:["_col0"]
> TableScan [TS_0]
>
> Output:["__time"],properties:{"druid.query.json":"{\"queryType\":\"timeseries\",\"dataSource\":\"druid_tpcds_ss_sold_time_subset\",\"descending\":false,\"granularity\":\"NONE\",\"aggregations\":[],\"intervals\":[\"1900-01-01T00:00:00.000Z/3000-01-01T00:00:00.000Z\"]}","druid.query.type":"timeseries"}
> {code}
> Thus, result has more than 10 rows.
