-----------------------------------------
Summary: Carbon1.3.0-Pre-AggregateTable -Query from segment set
is not effective when pre-aggregate table is present
Key: CARBONDATA-1736
URL: https://issues.apache.org/jira/browse/CARBONDATA-1736
Project: CarbonData
Issue Type: Bug
Components: data-load
Affects Versions: 1.3.0
Environment: Test - 3 node ant cluster
Reporter: Ramakrishna S
Fix For: 1.3.0
1. Create a table
create table if not exists lineitem3(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 queries and create pre-agg table queries in diff console:
load data inpath "hdfs://hacluster/user/test/lineitem.tbl.1" into table
lineitem3
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');
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;
0: jdbc:hive2://10.18.98.34:23040> select
l_returnflag,l_linestatus,sum(l_quantity),sum(l_extendedprice) from lineitem3
group by l_returnflag, l_linestatus;
+---------------+---------------+------------------+-----------------------+--+
| l_returnflag | l_linestatus | sum(l_quantity) | sum(l_extendedprice) |
+---------------+---------------+------------------+-----------------------+--+
+---------------+---------------+------------------+-----------------------+--+
