>                 Key: DRILL-5928
>                 URL: https://issues.apache.org/jira/browse/DRILL-5928
>             Project: Apache Drill
>          Issue Type: Bug
>    Affects Versions: 1.11.0
>            Reporter: Paul Rogers
>            Priority: Minor
>
> Consider the following test framework query:
> {noformat}
> /root/drillAutomation/mapr/framework/resources/Functional/data-shapes/wide-columns/general/q2.q
> {noformat}
> Defined as follows:
> {noformat}
> select count(*) from `data-shapes/wide-columns/general/100000.tbl`
> {noformat}
> The data file ({{100000.tbl}}) contains a single row, single field of 100K width. The query suceeds and returns 1.
> However, if we did the following:
> {noformat}
> select * from `data-shapes/wide-columns/general/100000.tbl`
> {noformat}
> then the query would fail with an oversize field exception. (Before Drill 1.13 the error is "Tried to write something large in a field", while 1.13 and after the error is "Text column is too large."
> The question is, should the query succeed in the {{COUNT\(*)}} case if it would fail in the {{SELECT *}} case?
