Manish Gupta created CARBONDATA-900:
---------------------------------------
Summary: Is null query on a newly added measure column is not
returning proper results
Key: CARBONDATA-900
URL: https://issues.apache.org/jira/browse/CARBONDATA-900
Project: CarbonData
Issue Type: Bug
Reporter: Manish Gupta
Assignee: Manish Gupta
Priority: Minor
Fix For: 1.1.0-incubating
When is null query is executed on newly added measure column, control goes to
RowLevelFilterExecuterImpl class, where measure existence is checked. In case
the measure is not found, bitset group is not getting populated with default
values due to which that block is not returning any result.
Below queries can be executed to reproduce the issue:
CREATE TABLE uniqdata110 (CUST_ID int,CUST_NAME String) STORED BY 'carbondata'
LOAD DATA INPATH '<csvfilePath>' into table uniqdata110
OPTIONS('BAD_RECORDS_LOGGER_ENABLE'='TRUE',
'BAD_RECORDS_ACTION'='FORCE','FILEHEADER'='CUST_ID,CUST_NAME')
ALTER TABLE uniqdata110 ADD COLUMNS (a6 int)
LOAD DATA INPATH '<csvfilePath>' into table uniqdata110
OPTIONS('BAD_RECORDS_LOGGER_ENABLE'='TRUE',
'BAD_RECORDS_ACTION'='FORCE','FILEHEADER'='CUST_ID,CUST_NAME,a6')
select * from uniqdata110
select * from uniqdata110 where a6 is null
Data:
7,hello1
8,welcome1
bye,11
