----------------------------------
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?
