> Currently, the `NettyBlockRpcServer` will reading data through BlockManager,
> while the block is not cached in memory, the data should be read from DISK
> first, then into MEM. I wonder if we implement a mechanism add a message
> contains the blockIds that the same as the openBlock message but one loop
> ahead, then the `NettyBlockRpcServer ` will load the block ready for transfer
> to the reduce side.
