---------------------------------
Summary: Screen operator silently ignores selection vector in its
incoming record batch
Key: DRILL-265
URL: https://issues.apache.org/jira/browse/DRILL-265
Project: Apache Drill
Issue Type: Bug
Reporter: Mehant Baid
Assignee: Mehant Baid
Priority: Minor
If any child of the Screen operator adds a selection vector to its record
batch. The screen operator ignores the selection vector and outputs all the
data (even the ones not present in the selection vector). It should do one of
the following
1. Throw an exception indicating it does not handle selection vector 2
2. Handle the selection vector. Project handles the selection vector, we could
possibly leverage some of the logic.
