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

             Summary: CSV text reader does not properly handle duplicate header names
                 Key: DRILL-5498
                 URL: https://issues.apache.org/jira/browse/DRILL-5498
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 1.8.0
            Reporter: Paul Rogers
            Priority: Minor


Consider the following CSV file:

{code}
h,h,h
a,b,c
d,e,f
{code}

Parse this with the CSV storage plugins to parse headers. The result:

{code}
2 row(s):
h
c
f
{code}

Expected a runtime error for the duplicate column names, or automatic "uniqification" of the names. Certainly did not expect the first two columns to be dropped.
