I am thinking of a case where, let's say two threads trying to read two different blocks using the same XceiverClientGrpc object as it is shared object, one thread issues a getBlock for block1 to dn1, dn1 got cached and further read chunk calls for all chunks for all blocks(block1 and block2) will go the same dn. The idea of shuffling the datanodes was basically to distribute the load across the datanodes in a pipeline, but for the same block it should always be tried on the same order of datanodes. I think the patch won't address both these concerns here. What do you think?
