Ravindra Pesala resolved CARBONDATA-2045.
-----------------------------------------
Resolution: Fixed
> Query from segment set is not effective when pre-aggregate table is present
> ---------------------------------------------------------------------------
>
> Key: CARBONDATA-2045
> URL: https://issues.apache.org/jira/browse/CARBONDATA-2045
> Project: CarbonData
> Issue Type: Bug
> Reporter: kumar vishal
> Assignee: kumar vishal
> Priority: Major
> Time Spent: 3.5h
> Remaining Estimate: 0h
>
> 1. Create a table
> create table if not exists lineitem1(L_SHIPDATE string,L_SHIPMODE
> string,L_SHIPINSTRUCT string,L_RETURNFLAG string,L_RECEIPTDATE
> string,L_ORDERKEY string,L_PARTKEY string,L_SUPPKEY string,L_LINENUMBER
> int,L_QUANTITY double,L_EXTENDEDPRICE double,L_DISCOUNT double,L_TAX
> double,L_LINESTATUS string,L_COMMITDATE string,L_COMMENT string) STORED BY
> 'org.apache.carbondata.format' TBLPROPERTIES
> ('table_blocksize'='128','NO_INVERTED_INDEX'='L_SHIPDATE,L_SHIPMODE,L_SHIPINSTRUCT,L_RETURNFLAG,L_RECEIPTDATE,L_ORDERKEY,L_PARTKEY,L_SUPPKEY','sort_columns'='');
> 2. Run load :
> load data inpath "hdfs://hacluster/user/test/lineitem.tbl.1" into table
> lineitem1
> options('DELIMITER'='|','FILEHEADER'='L_ORDERKEY,L_PARTKEY,L_SUPPKEY,L_LINENUMBER,L_QUANTITY,L_EXTENDEDPRICE,L_DISCOUNT,L_TAX,L_RETURNFLAG,L_LINESTATUS,L_SHIPDATE,L_COMMITDATE,L_RECEIPTDATE,L_SHIPINSTRUCT,L_SHIPMODE,L_COMMENT');
> 3. create pre-agg table
> create datamap agr_lineitem3 ON TABLE lineitem3 USING
> "org.apache.carbondata.datamap.AggregateDataMapHandler" as select
> L_RETURNFLAG,L_LINESTATUS,sum(L_QUANTITY),sum(L_EXTENDEDPRICE) from lineitem3
> group by L_RETURNFLAG, L_LINESTATUS;
> 3. Check table content using aggregate query:
> select l_returnflag,l_linestatus,sum(l_quantity),sum(l_extendedprice) from
> lineitem3 group by l_returnflag, l_linestatus;
> +----------------+--------------++------------------------------------------++--

> 6. Set query from segment 1:
> 0: jdbc:hive2://10.18.98.48:23040> set
> carbon.input.segments.test_db1.lilneitem1=1;
> +---------------------------------------------+-------++--
> |key|value|
> +---------------------------------------------+-------++--
> |carbon.input.segments.test_db1.lilneitem1|1|
> +---------------------------------------------+-------++--
> 7. Check table content using aggregate query:
> select l_returnflag,l_linestatus,sum(l_quantity),sum(l_extendedprice) from
> lineitem3 group by l_returnflag, l_linestatus;
> *+Expected+*: It should return the values from segment 1 alone.
> *+Actual :+* : It returns values from both segments
