             Summary: Fixed length value vectors report invalid value count
                 Key: DRILL-2611
                 URL: https://issues.apache.org/jira/browse/DRILL-2611
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Hanifi Gunes
            Assignee: Hanifi Gunes


We maintain an exclusive value count variable in fixed vectors however we don't update it upon calling set/Safe. Accessor reports the value count from the variable ignoring values that are already in the buffer or written via set/Safe. This causes execution failures manifested as IOOB when underlying data is sparse. We should either remove the variable and report value count directly investigating the buffer if not computationally expensive or update the variable each time we make a write to the vector.
