             Summary: Drill allows a COUNT(*) over records that are two wide to load
                 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?
