Subject [jira] [Created] (PHOENIX-3530) Queries with 'like/wildcard %' in the predicate not returning all rows

Duane Lupinski created PHOENIX-3530:
---------------------------------------

             Summary: Queries with 'like/wildcard %' in the predicate not returning all rows
                 Key: PHOENIX-3530
                 URL: https://issues.apache.org/jira/browse/PHOENIX-3530
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.4.0
         Environment: Red Hat Enterprise Linux Server release 6.5
            Reporter: Duane Lupinski


Here is the background: 

This query returns back 18 rows 
. 
select rowkey_i, evt_d, rawevt_fk from tep_own.event_trace where rowkey_i like '2016102709%CSXT000102%_GPS_ATS';


If I look at the unique rawevt_fks it returns back 6 unique rows 

select distinct rawevt_fk from tep_own.event_trace where rowkey_i like '2016102709%CSXT000102%_GPS_ATS';


If I query the table with a wildcard it returns back only 2 rows when it should be 5 (one
of the 6 has a row key with the hour as 08 instead of 09)
 
select * from tep_own.raw_event where rowkey_i like '2016102709%_CSXT000102_GPS_ATS'; 

If I query one of those rows comparing the rowkey directly using the equals sign I get the
row back as I should. 

select * from tep_own.raw_event where rowkey_i = '20161027095735327_CSXT000102_GPS_ATS'; 

However, if I do the same query with a wildcard nothing comes back: 

select * from tep_own.raw_event where rowkey_i like '20161027095735327_CSXT000102_GPS_%';


If I use the in clause to list each of the rawevt fks all rows are returned:
 
select * from tep_own.raw_event where rowkey_i in 
( '20161027085735178_CSXT000102_GPS_ATS', 
'20161027091035210_CSXT000102_GPS_ATS', 
'20161027092736742_CSXT000102_GPS_ATS', 
'20161027093835903_CSXT000102_GPS_ATS', 
'20161027094724722_CSXT000102_GPS_ATS', 
'20161027095735327_CSXT000102_GPS_ATS') ; 

So, it looks like the data is there as long as you query it directly without using a wildcard.
When using a wildcard we are getting mixed results in what is returned.
