[jira] [Created] (DRILL-2185) flatten(*) should return a more appropriate error

Rahul Challapalli created DRILL-2185:
----------------------------------------

             Summary: flatten(*) should return a more appropriate error
                 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)
            Priority: Minor


git.commit.id.abbrev=c54bd6a

The below query returns an obscure error
{code}
0: jdbc:drill:schema=dfs> select flatten(*) from `data1.json`;
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
