Frans Drijver created HIVE-4662:
-----------------------------------

             Summary: first_value can't have more than one order by column
                 Key: HIVE-4662
                 URL: https://issues.apache.org/jira/browse/HIVE-4662
             Project: Hive
          Issue Type: Bug
          Components: SQL
    Affects Versions: 0.11.0
            Reporter: Frans Drijver


In the current implementation of the first_value function, it's not allowed to have more than
one (1) order by column, as so:

{quote}
select distinct 
first_value(kastr.DEWNKNR) over ( partition by kastr.DEKTRNR order by kastr.DETRADT, rettr.DEVPDNR
)
from RTAVP_DRKASTR kastr
;
{quote}

Error given:

{quote}
FAILED: SemanticException Range based Window Frame can have only 1 Sort Key
{quote}
