Liam De Lee updated HIVE-19943:
-------------------------------
Description:
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.
