appropriate error
Rahul Challapalli created DRILL-2185:
----------------------------------------

Key: DRILL-2185
URL: https://issues.apache.org/jira/browse/DRILL-2185
Project: Apache Drill
Issue Type: Bug
Components: Functions - Drill
Reporter: Rahul Challapalli
Assignee: Daniel Barclay (Drill/MapR)

git.commit.id.abbrev=c54bd6a
The below query returns an obscure error
{code}

Query failed: AssertionError: Internal error: invariant violated: conversion result not null
{code}
We should mention that it is an in-appropriate use of the flatten operator
