> 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.
