> Clients should be able to provide their own BufferAllocator to
> LlapBaseInputFormat if allocator operations depend on client-side logic. For
> example, clients may want to manage the allocator hierarchy per client-side
> task, thread, etc..
> Currently the client is forced to use one global RootAllocator per process.
