    Description

      Disabling spilling joins via the "-enable_partitioned_hash=false" impalad startup flag does not work as expected because RIGHT SEMI/ANTI JOIN and the NULL AWARE LEFT ANTI JOIN will still use the spilling operator. So even if the startup flag is set, spilling on joins can occur.
