What's Wrong?

for now, we just support source as join build source, in distributed mode, we will collect unmatched rows from hash table. This will cause two problems:

  1. if it's not a hash join, we can't retrieve data from hash table.
  2. if source is large, we trigger spill in the future, and we can't collect from memory hash table.

How to Reproduce?
