             Summary: Json reader throws IndexOutOfBoundsException
                 Key: DRILL-282
                 URL: https://issues.apache.org/jira/browse/DRILL-282
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Mehant Baid
            Assignee: Timothy Chen


Trying to scan the following json file 

{
  "Bigname": [ {"name": "hello", "id": "1"}, {"name": "world", "id": "2"}]
}

using a simple query (via sqlline): select * from "filename.json"; results in 
the following error

java.lang.IndexOutOfBoundsException

The same query works if the above json file is modified to be the following:

{
  "Bigname": [ {"name": "hello", "id": "1"} ]
}
