Answer 1

Did I understand correctly that data structure is: INPUT - SOURCE - LOCAL_HOSTNAME ?
If so, add two spaces after SOURCE: Item.
-- Edited according to the comment.
yml config in presented format is highly dependant on tabulations.
So, working config might look as follows:

VERSION: 1.0.0.1 
DATABASE: gpadmin
USER: gpadmin
HOST: gpdbsne
PORT: 5432
GPLOAD:
  - INPUT:
    - SOURCE:
      LOCAL_HOSTNAME: gpdbsne
      PORT: 8999
      FILE: /home/gpadmin/testfile.txt
    - FORMAT: text 
    - DELIMITER: '|'
    - QUOTE: '"'
    - COLUMNS:
      - col1: text
      - col2: text
      - col3: text
      - col4: text
      - col5: text
  - OUTPUT:
    - TABLE: public.test
    - MODE: insert 
    - MAPPING:
      - col1: col1
      - col2: col2
