[jira] [Updated] (HIVE-11735) Different results when multiple if() functions are used

2015-09-04 Thread Chetna Chaudhari (JIRA)

Chetna Chaudhari updated HIVE-11735:

Description: 
Hive if() udf is returns different results when string equality is used as 
condition, with case change. 
Observation:
   1) if( name = 'chetna' , 3, 4) and if( name = 'Chetna', 3, 4) both are 
treated as equal.
   2) The rightmost udf result is pushed to predicates on left side. Leading to 
same result for both the udfs.

How to reproduce the issue:
1) CREATE TABLE `sample`(
  `name` string)
ROW FORMAT SERDE
  'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe'
STORED AS INPUTFORMAT
  'org.apache.hadoop.mapred.TextInputFormat'
OUTPUTFORMAT
  'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'
TBLPROPERTIES (
  'transient_lastDdlTime'='1425075745');

2) insert into table sample values ('chetna');
3) select min(if(name = 'chetna', 4, 3)) , min(if(name='Chetna', 4, 3))  from 
sample; 
This will give result : 
33
Expected result:
43
4) select min(if(name = 'Chetna', 4, 3)) , min(if(name='chetna', 4, 3))  from 
sample; 
This will give result 
44
Expected result:
34
