>
> 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.
