                 Key: KYLIN-1522
                 URL: https://issues.apache.org/jira/browse/KYLIN-1522
             Project: Kylin
          Issue Type: Bug
    Affects Versions: v1.5.0
            Reporter: liyang
            Assignee: hongbin ma


The query result of HLLC is incorrect -- being a constant value across multiple 
rows -- when the result is read from cache.

The cause is likely multiple rows in cache is referencing the same HLLC counter 
object.
