> RuntimeFilter's BF ByteBuf ownership should be transferred right at broadcast and random hash cases. Currently due to we not treat this transferring reasonable, it caused the memory leak.
> To broadcast case,the HashJoin operator's allocator allocated the BF, the allocated BF's ownership should be transferred to its receiver : the FragmentContextImpl or the final RuntimeFilter operator. Otherwise, the OperatorContextImpl's close method will complain about the memory leak when closing the corresponding allocator.
