the write pipeline is closed when a error is encountered and the faulty
node is taken out of the pipeline and the write continues.Few other
intermediate steps are to move the un-acked packets from ack queue to the
My question is , is this faulty data node is reported to the NN and whether
NN would continue to use it as a valid DN while serving other write
requests in future or will it make it as faulty ?
