----------------------------------------

             Summary: IllegalArgumentException while reading JSON files
                 Key: DRILL-4180
                 URL: https://issues.apache.org/jira/browse/DRILL-4180
             Project: Apache Drill
          Issue Type: Bug
          Components: Storage - JSON
            Reporter: Sean Hsuan-Yi Chu
            Assignee: Sean Hsuan-Yi Chu
             Fix For: 1.5.0
         Attachments: a.json, b.json

First of all, this issue can be reproduced when drill runs on distributed mode.

We have two json files in distributed file system. The type for the column is MAP and there is not schema change on the top level. However, in the one layer deeper in this column, the first file has one NullableBit column, which does not appear in the second file. 

The issue can be reproduced by the files in the attachment and this query :
{code}
select jsonFieldMapLevel1_aaa from directory
{code}
