[jira] [Created] (CARBONDATA-2155) IS NULL not working correctly on
string datatype with dictionary_include in presto integration
Sangeeta Gulia created CARBONDATA-2155:
------------------------------------------
Summary: IS NULL not working correctly on string datatype with dictionary_include in presto integration
Key: CARBONDATA-2155
URL: https://issues.apache.org/jira/browse/CARBONDATA-2155
Project: CarbonData
Issue Type: Bug
Components: presto-integration
Affects Versions: 1.3.0
Environment: Spark-2.1
Presto 0.187
Reporter: Sangeeta Gulia
Attachments: lineitem.csv
Steps to reproduce:
1) Create table on carbondata and load data to it.
create table if not exists lineitem_carbon1(
L_SHIPDATE date,
L_SHIPMODE string,
L_SHIPINSTRUCT string,
L_RETURNFLAG string,
L_RECEIPTDATE date,
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 date,
L_COMMENT string
) STORED BY 'carbondata'
TBLPROPERTIES ('DICTIONARY_INCLUDE'='L_SHIPMODE,L_SHIPINSTRUCT,L_RETURNFLAG,L_LINESTATUS', 'table_blocksize'='300', 'no_inverted_index'='L_ORDERKEY, L_PARTKEY, L_SUPPKEY, L_COMMENT');
load data inpath "hdfs://localhost:54310/user/hduser/input-files/lineitem.csv" into table lineitem_carbon1 options('DATEFORMAT' = 'yyyy-MM-dd','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','BAD_RECORDS_LOGGER_ENABLE'='true', 'BAD_RECORDS_ACTION'='FORCE');
1: jdbc:hive2://localhost:10000> select l_shipmode from lineitem_carbon1 where l_shipmode is NULL;
+-------------+--+
| l_shipmode |
+-------------+--+
| NULL |
+-------------+–+
2) Access the same table from presto-cli and try to run select query form there:
presto:performance> select l_shipmode from lineitem_carbon1 where l_shipmode is NULL;
l_shipmode
------------
(0 rows)
Expected Result: It should be same as result from carbon.
