---------------------------------------

             Summary: Vectorization: query with regex gives incorrect results with vectorization
                 Key: HIVE-21503
                 URL: https://issues.apache.org/jira/browse/HIVE-21503
             Project: Hive
          Issue Type: Bug
          Components: Vectorization
            Reporter: Rajesh Balamohan


i see wrong results with vectorization. Without vectorization, it works fine. Suspecting minor issue in {{StringGroupColConcatCharScalar}}
{noformat}
e.g 

WHEN x like '%radio%' THEN 'radio' 
WHEN x like '%tv%' THEN 'tv'
{noformat}
