      Description

      The result of TPC-DS query 11 in Impala is wrong. It lost a record :
      "AAAAAAAAOPDLAAAA | Ann | Pence N"

      I'm using tpcds 1g validation dataset generated by command:
      "./dsdgen -sc 1 -terminate N -validate Y"
      with tpc-ds-2.3.0

      Attachments are the query string, result of Impala and tpc-ds answer set.

      Note: I have also run this query in PostgreSQL and it gives the same result as tpc-ds result set.
