result = hiveContext.sql("select linestatus, sum(quantity) as sum_qty,count(*) as count_order from lineitem 
where shipdate <= '1990-09-16' group by linestatus order by

Answer 1

mehrzeilige Strings in Scala haben dreifache Anführungszeichen eingeschlossen werden:

hiveContext.sql(""" 
    select linestatus, sum(quantity) as sum_qty,count(*) as count_order 
    from lineitem 
    where shipdate <= '1990-09-16' group by linestatus order by linestatus""")
