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

             Summary: Header values keep showing up in result sets
                 Key: HIVE-19943
                 URL: https://issues.apache.org/jira/browse/HIVE-19943
             Project: Hive
          Issue Type: Bug
          Components: Query Processor
    Affects Versions: 2.1.0
         Environment: Hdinsight Hive interactivequerry

We are using the tblproperties ("skip.header.line.count"="1") when creating an external table.

When we do a select * from table we get it back as expected without the header present in the result set.

However when we do for instance a count(1) we get the header back in this count (tested with a select * from table and paste it in notepad to find the amount of rows)

If we also do this with a select distinct(column) from table we also get the header as a distinct value.
