Subject [jira] [Commented] (DRILL-265) Screen operator silently ignores selection vector in its incoming record batch
Date Mon, 02 Dec 2013 04:56:42 GMT

    [ https://issues.apache.org/jira/browse/DRILL-265?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13836240#comment-13836240

Jacques Nadeau commented on DRILL-265:
--------------------------------------

Build fails when applying to latest master.  Can you figure out what is wrong?  Looks like
maybe another test is violating this rule.

> 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.
