Hi, I was going through some documents about HDFS write pattern. It looks like 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 data queue.
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 ? Thanks, Rahul
