Manish Gupta created CARBONDATA-1934:
----------------------------------------

             Summary: Incorrect results are returned by select query in case when the number
of blocklets for one part file are > 1 in the same task
                 Key: CARBONDATA-1934
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-1934
             Project: CarbonData
          Issue Type: Bug
            Reporter: Manish Gupta
            Assignee: Manish Gupta


When a select query is triggered, driver will prune the segments and give a list of blocklets
that need to be scanned. The number of tasks from spark will be equal to the number of blocklets
identified.
In case where one task has more than one blocklet for same file, then BlockExecution getting
formed is incorrect. Due to this the query results are incorrect.
