----------------------------------------
Assignee: Kunal Kapoor
> Carbon1.3.0-Pre-AggregateTable - Query returns no value if run at the time of
> pre-aggregate table creation
> ----------------------------------------------------------------------------------------------------------
>
> Key: CARBONDATA-1743
> URL: https://issues.apache.org/jira/browse/CARBONDATA-1743
> Project: CarbonData
> Issue Type: Bug
> Components: data-load
> Affects Versions: 1.3.0
> Environment: Test - 3 node ant cluster
> Reporter: Ramakrishna S
> Assignee: Kunal Kapoor
> Labels: DFX
> Fix For: 1.3.0
>
>
> Steps:
> 1. Create table and load with large data
> create table if not exists lineitem4(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'='');
> load data inpath "hdfs://hacluster/user/test/lineitem.tbl.1" into table
> lineitem4
> 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');
> 2. Create a pre-aggregate table
> create datamap agr_lineitem4 ON TABLE lineitem4 USING
> "org.apache.carbondata.datamap.AggregateDataMapHandler" as select
> L_RETURNFLAG,L_LINESTATUS,sum(L_QUANTITY),sum(L_EXTENDEDPRICE) from lineitem4
> group by L_RETURNFLAG, L_LINESTATUS;
> 3. Run aggregate query at the same time
> select l_returnflag,l_linestatus,sum(l_quantity),sum(l_extendedprice) from
> lineitem4 group by l_returnflag, l_linestatus;
> *+Expected:+*: aggregate query should fetch data either from main table or
> pre-aggregate table.
> *+Actual:+* aggregate query does not return data until the pre-aggregate
> table is created
> 0: jdbc:hive2://10.18.98.48:23040> select
> l_returnflag,l_linestatus,sum(l_quantity),sum(l_extendedprice) from lineitem4
> group by l_returnflag, l_linestatus;
