-----------------------------------
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.
